BOBBIN SPECIFICATIONS
Bobbin Types
The bobbins in this catalog have been
manufactured to match the industry’s popular
ferrite, powder and lamination core shapes and
sizes. All the critical bobbin characteristics are
included in these pages and on the drawing for
each bobbin. The best shape is usually a tradeoff between heat dissapation, magnetic shielding,
cost, the ease of winding, and assembly.

solder temperature go up, thermoset materials are
more popular.

RoHS Compliance
Restrictions on Hazardous Substances (RoHS) is
a European inspired regulation that limits 6 harmful
ingredients for electronic components. Flame
retardants in the plastic material and lead in the
tin/lead (Sn/Pb) plated terminals are included on the
list of harmful ingredients. Most plastic manuracturers
have re-formulated their plastic to meet RoHS and
terminals are now lead free. All bobbins that meet the
requirements of RoHS are clearly marked in these
pages and on the drawing for each bobbin.

UL94 Flammability Rating
A plastic’s ability to resist burning, or its flammability rating, is also a critical factor. Underwriter’s
Laboratory (UL) has specific flammability requirements depending on the working environment of
the finished product. Referred to as UL94, this
regulation classifies plastic materials on their ability
to self extinguish when put in contact with, and then
removed from an open flame. In most applications,
the highest level of UL94VO is preferred.
V5
Will support combustion for
up to 60 seconds after 5 test
burnings of 5 seconds each
and self extinguishes when
tested under specific conditions.
HB
Will support combustion and may
not self extinguish when tested
under specific conditions.
