frequency power conversion inductors, noise filters and various
tuned circuit applications to meet their design objectives. To
assist in this selection process, we have included the following
information:
• How
to order parts
information
• Formulas and definitions for design calculations
• Comparative magnetic curves for performance evaluation
• Electrical and physical specifications with part numbers
• ”Q“ curves for Molybdenum Permalloy Powder cores

Design Information
Molybdenum Permalloy, Hi-Flux and Super-MSS Powder cores
are wound with magnet wire to make transformers or inductors.
Maximum allowable energy dissipation for a given value of
energy storage (inductance and current) or transformation
(voltage and current), guide the selection of core material and
size. Energy dissipation is usually specified in terms of maximum
temperature rise, minimum efficiency or minimum Q value. (Q is
2π times the ratio of peak energy stored to energy dissipated
during one period of current flow.) Consider the following when
choosing a core material:
1. Molybdenum Permalloy Powder (MPP) cores provide the
maximum Q and lowest core loss. MPP is the most stable core
with respect to temperature and AC Flux. It has the widest
range of permeabilities and is considered the premium
material for direct current output inductors of Switched Mode
Power Supplies. It is useful into the Megahertz range of
frequencies. MPP cores are an excellent choice for precision
audio frequency tuned circuits, High Q Filters, Loading Coils,
RFI Filters and many other precision inductor applications.
2. Hi-Flux cores are a 50% Nickel 50% Iron distributed gapped
powder core. HF has up to 15,000 Gauss saturation flux density
and core losses significantly lower than iron powder cores. These
cores are ideal for Switching Regulator Inductors, In Line Noise
Filters, Pulse and Fly-Back Transformer applications. When used in
applications with high dc current, HF cores can provide a reduction
in inductor size as well as total cost.
3. Super-MSS is an improved Sendust material, originally
developed by Arnold Engineering. It is designed to replace iron
powder by offering much lower losses, with energy storage
capability higher than MPP. Super-MSS cores are an excellent
choice for energy storage and filter inductor applications in
Switch Mode Power Supplies. The low loss properties of SuperMSS cores minimizes the temperature rise at power frequencies
to well below that of a similar sized iron powder core. The DC
Bias characteristics of Super-MSS are also excellent compared
to iron powder of similar permeabilities and size.
For reference, some basic electromagnetic terms and relationships
used to design with magnetic powder cores are defined, followed
by graphs showing typical values for material characteristics
essential to transformer and inductor design. The final section of
this catalogue contains data for specific core sizes and Q curves
for Molybdenum Permalloy Powder (MPP) cores.
Units of Measure
For historical reasons, the Centimeter-Gram-Second (CGS) system is
used in this catalog. Conversion between the System International
(SI) and CGS System is simplified using the following table.

Also, free space permeability in the CGS System has a
magnitude of 1 and no dimensions. Free space permeability is
4π x 10-7 henries per meter in the System International.
Inductance
Inductance (L) is calculated using the inductance factor (AL ) listed
for each core.
L
= ALN2 nanohenries
A L = inductance factor in mH for 1000 turns.
N = number of turns.
Therefore,
N=

where L is in nanohenries.
Inductance can also be determined from the relative permeability
(referred to in this catalog as µ, “permeability” and “perm”) and
the effective core parameters shown in Figure 1.

A e = effective core area in square centimeters.
le = effective magnetic path length in centimeters.

Design Information (Cont.)
The “Normal Permeability versus Flux Density” graph shows
normal permeability as a function of peak flux density, B.
le
Most design procedures involve choosing a peak operating
magnetic flux density to help determine the core size. Peak
operating flux density is limited by the core material saturation
flux density or by the core material loss. After choosing the
material and operating flux density and determining the core
size, Faraday’s Law (discussed below) is then used to calculate
the number of turns, N. Finally, a permeability is selected to
provide the required inductance.
Figure 1.

For toroidal powder cores, the effective area is the same as the
cross sectional area. By definition and Ampere’s Law, the effective
magnetic path length is the ratio of winding ampere-turns (NI) to
the average magnetizing force across the core area from inside
diameter to outside diameter. Using Ampere’s Law and averaging
the magnetizing force gives the formula for effective path length.

A wide range of permeabilities are offered to satisfy various
inductance requirements.
O.D. = outside diameter of core.
I.D. = inside diameter of core.
Ampere’s Law (also discussed below) gives the peak value of
magnetizing force, H, based on the number of turns, peak
magnetizing current (the total current of an inductor and
“no-load” current in a transformer primary) and core magnetic
path length. As can be seen in Figure 2, selecting the
permeability sets the peak magnetic flux density so it matches
the value chosen at the beginning of the design procedure. Also,
for Molybdenum Permalloy Powder (MPP), the following
selection chart gives the permeability that yields maximum
inductance for a given magnetizing force.
Inductance factors are measured using a single layer winding
with closely spaced turns. Flux densities and test frequencies are
kept as low as practical, usually less than 40 gausses and 10 kHz
or below. The “Normal Permeability versus Flux Density” and
“Typical Permeability versus Frequency” graphs can be used as
guides to define low-level test conditions for the various
permeabilities and materials.

INCRMENTAL PERMEABILITY
The inductance factors listed for each core size are based on
incremental relative permeabilities. With no direct current bias
and at low flux densities, the normal and incremental
permeabilities are the same. The incremental permeability
decreases with direct current bias as indicated by Figure 2 and
shown in the “Incremental Permeability versus DC Bias” graphs.

Design Information (Cont.)
The “Normal Magnetization Curves” can be used with the
“Typical Incremental Permeability versus DC Bias Curves” to
estimate the direct current magnetic flux density for a chosen
percentage of incremental permeability. For example, 125µ
Molybdenum Permalloy Powder has 50% incremental
permeability at just under 50 oersteds. The corresponding flux
density is about 4500 gausses (0.45 tesla) according to the
normal magnetization curve. Surveying the other permeabilities
suggests that this could be used as an approximation of the DC
flux density where Molybdenum Permalloy Powder has 50% of
its original incremental permeability.

The effective area is considered the total area of the core cross
section as shown in Figure 1. The area occupied by magnetic
alloy is less than this area and decreases with decreasing
permeability. Catalog data for the different permeabilities include
effects from the smaller magnetic alloy areas.
Also, Bmax is an average maximum flux density value over the
core cross section. The flux density is greater toward the inside
diameter and smaller toward the outside diameter as shown by
Ampere’s Law and described in the following.

Winding Notes
The d.c. winding resistance for an average winding can be
calculated by:
Molypermalloy Q Curves“.) The graph below is useful for
estimating self-resonant frequency. By selecting a winding
technique which minimizes the voltage between turns, the
distributed capacitance may be reduced. Several winding
techniques are available. Dividing the winding into a number of
sections, such as 2, 4, or more, or the use of a bankwound coil
is effective in reducing the capacitance. In any case, the winding
and inter-sector connecting technique should carefully avoid
placing the first and last turns adjacent to each other - as they
have the highest turn to turn potential, and thus contribute the
most to the effective capacitance. Both the moisture content in
the dielectric of the winding and the dielectric constant of
potting and encapsulating materials increase the effective
distributed capacitance.
Rdc = l w Nr
12000
l w = mean length of turn (in.)
N = number of turns
r = resistance of wire in ohms per 1000 feet
(see wire table on page 8.)
In addition to the normal d.c. resistance of a winding, there
exists an incremental change in the winding resistance due to
the skin effects of a.c. current.* This can be approximated by:
Precision wound cores - stable with time and having
reproducible temperature characteristics - must have winding
strains relieved by temperature cycling. The wound cores must
be cycled from room temperature to 125° C., repeating the cycle
as many times as necessary to achieve reproducible results. At
least one cycle should include a temperature lower than the
wound core will be exposed to under operating conditions. This
cycling will not only relieve strains, but also remove moisture that
is present. Final adjustment of inductance value should be made
after the temperature cycling process has been completed.

d = wire diameter (inches)
f = frequency (HZ)
°C = operating temperature
The wound cores should be kept dry until they are dipped, potted, or
hermetically sealed. Potting and encapsulating compounds should be
carefully selected as some may shrink with age or temperature
change, and thus affect stability. Cushioning material on the wound
cores can minimize this effect.
Minimizing distributed capacitance is an important core winding
consideration. A toroidal winding has an effective capacitance
which may be considered to be in parallel with the inductance.
This is the result of the summation of capacitances from turn to
turn, layer to layer, and from parts of the winding to the core.
(The effect of this capacitance on the Q and the inductance of
the component is discussed in the section ”Notes on

Notes on Molybdenum Permalloy Q Curves
Note: The following information applies to
frequency tuned circuit applications.
The Q formula calculates the ratio of reactance to effective
resistance for an inductor and thus indicates its quality. For
electrical wave filters, an increase in Q provides sharper cut-off,
higher attenuation ratios, and better defined resonance. Q is
affected by the distributed capacitance of an inductor's winding.
Neglecting the effects of self-resonance caused by the
distributed capacitance (see paragraph 4c, below) Q can be
calculated, when designing inductors, by this formula: **
Q=
Q =
L =
=
Rdc =
Rac =
Rcd =
L
Rdc + Rac + Rcd
quality factor
inductance (henries)
2 π X frequency (frequency in hertz)
dc winding resistance (ohms)
resistance due to core losses (ohms)
resistance due to dielectric losses in winding (ohms)
The Q curves published in this manual are not to be construed as
guaranteed minimum values. Instead they represent what might
be attainable under ideal conditions. They were developed
theoretically and have been checked with various core sizes and
inductances to assure reasonable correspondence to the real
world of wire, insulation and winding. The user's ability to get
equivalent results depends in part upon his ability to duplicate
the assumed conditions.
These are:
1. A "full-wound core" is defined to be one in which the
minimum winding ID or residual hole left after winding is
one-half of the inside diameter of the core.
b. The second factor is caused by dielectric loss. Dielectric loss
resistance is significant at higher frequencies and can be
calculated from the equation found in Terman’s Handbook.***

= 2π X frequency in hertz
L = Inductance in henries
Cd = distributed capacitance in farads
c. The most dramatic factor is the effect of self resonance of the
distributed capacitance and the inductance. For small
inductances, such as the 0.001 henry or the 0.01 henry curve
for each core, the self-resonant frequency f° is well above the
normal useful frequency range of the component. Therefore,
these curves tend to indicate the component performance with
a negligible effect of self resonance. The distributed capacitance
and the self inductance determine a self-resonant frequency
according to:
f° =
Qf = Q

analysis follows Herman Blinchikoff, ”Toroidal Inductor Design,”

( f° (
where Q is calculated from determined values of loss
resistances as indicated above, and Qf is the apparent Q,
taking into account the effect of the distributed
capacitance. It should be noted that when f is 20% of f°,
Qf is 96% of its original value. However, when f is 70% of
f°, Qf drops to 51% of its original value. The apparent
value of the inductance, La, is also affected as follows:
L
La =
4. Three factors affect the high frequency performance of
an inductor.
a. The most fundamental is the loss of the core material
which is mostly responsible for the negative slope of the
low inductance curves at frequencies above the frequency
of maximum Q. This is calculated from Legg's equation
(see next section).
hertz.
2 π LC d
At some lower frequency, f, the value Qf can be
calculated from:
2. This leaves a useful winding area which is three-quarters of
the available window area. It was assumed that 70% of this
space would be filled with copper wire including heavy
synthetic film insulation.
3. The dc resistance of a full-wound core varies as the square of
the number of turns in the same manner that the resultant
inductance varies as the square of the turns. Therefore, each
core size has a table of calculated ohms per millihenry based
on the "full-wound core" definition above. This resistance
determines the positive slope of the low frequency portion of
the Q curve and is assumed to be independent of inductance.

5. Because the distributed capacitance is determined by the
winding method, the user can obtain different results from
those plotted, depending on this value of the capacitance.
Each Q curve is marked with the capacitance value used.

Molybdenum Permalloy Core Loss
at Low Magnetic Flux Densities
LEGG'S EQUATION1...total core loss at low flux densities is the
sum of three component losses - hysteresis, residual and eddy
current. Values of typical loss coefficients are found in the
following table for each permeability. The core loss in terms
of ohms per henry per unit of permeability is calcuated from
Legg's Equation:
