SAFETY CERAMIC DISC CAPACITORS - KZ SEREIS
Description
Safety ceramic disc KZ capacitors are intended for the galvanic separation of
mains and conductive parts that might be touched, i.e. antenna inputs in radio
and TV sets. They are ideal for line by-pass, antenna coupling and acrossthe-line applications, especially for circuits exposed to the danger of electric
shock. These capacitors meet safety rules applicable to electronic apparatus
and associated fittings for domestic or similar general use, connected to mains
according to EN 132400.
KZ capacitors offered by KEKO VARICON cover a capacitance range from 330 pF
to 4700 pF, operating at AC rated voltages 300 V for Y2 Class and 500 V for Y1
and X1 Classes at frequency of 50 Hz.
KEKO VARICON presently offers two groups of Type 2 KZ capacitors: group KZL –
Class Y2 and Class X1 which can withstand a test voltage of 2.5 kV AC and group
KZH – Class Y1 and Class X1 which can withstand a test voltage of 4 KV AC.

ASSEMBLY RECOMMENDATIONS FOR TH COMPONENTS
Very often before soldering through-hole components, their leads get bent. It is important not to damage the component during lead bending. Typical damage incurred during
bending is cracks in epoxy parts, which can lead to increased humidity sensitivity of a
component and consequentially to a shorter life time.
In order to avoid epoxy parts damage it is necessary to:
- fix the most sensitive point (epoxy parts) of a component body
- bend the wire at least 2 mm below the end of epoxy parts
Other potential damage to a component which can lead to component failure or a shorter life time is thermal shock during manual soldering with a soldering iron. This can occur
in the case when a soldering iron is placed too close to one point of the component body
and most often it happens if the solder joint is too close to the varistor body.
° Resistance to Soldering Heat
In the case of automatic wave soldering, it is important to provide sufficient resistance
to soldering heat. In order to prevent any potential problems KEKO VARICON decided
to introduce their own internal standard for testing the resistance to soldering heat of
through-hole components: 300 °C, 10s.
° Pb-free Wave Soldering Profile Recommendations
Recommended soldering profiles for all above components are in accordance with
JEDEC standard curves (J-STD-020D) and therefore compatible with the new Pb-free
process.

Following the final heat treatment all Type 2 ceramic capacitors reduce their capacitance
value according to logarithmic law due to their special crystalline structure. This change
is called ageing. If the capacitor is heated, for example during soldering, the capacitance
value increases tohigher value and the aging process begins again. The level of de-ageing
depends on temperature and duration of the heat - for example an almost complete deaging is achieved at 150°C in one hour. These conditions are also the basis for reference
measurements for any testing.
Ageing constant is defined as
capacitance change per time decade. Ageing constant differs for various types of ceramics.
For 2E3 and 2F3 ceramics used for RFI suppression and safety capacitors ageing constant
ranges from -3 to -5%.

Reference
Measurements
Due to ageing it is necessary to quote an age for reference measurements which can
be related to the capacitance with the fixed tolerance. As defined in CECC 30700 this
age is 1000 H. If the age of the capacitor is known, the capacitance for T=100 h can be
calculated using known ageing constant:
K= 100 (C1-C2)/[C1*log
t1/t2] => C2 = C1*[1-k/(100*log(t1/t2))], where k is ageing constant in %, t1, t2 are
measurement time points and C1, C2 capacitance values at time t1 and t2 respectively.
It is important to de-age the capacitors before any stress testing, so that the changes
as a result of the test are not affected by age. The following procedure should be used
for any stress measurements (according to CECC 30700, appendix B):
- de-aging at 150 °C, 1h
- storage: 24h at 20-25 °C, 50-70 % RH
- initial measurements
- stress test
- de-ageing at 150 °C
- storage: 24h at 20-25 °C, 50-70 % RH
- final measurements
