Automotive Stable MOV Electrical Components, Impact-Resistant
Low-Voltage Varistor 32D Series 32D821K 32D471K 32D681K Mu
SPD varistor manufacturers believe that varistors have strong
electrical characteristics and are a very mature electronic
component that can be used in various electronic equipment to
protect the claws, reduce lightning damage, and help improve the
stability of the equipment It can be applied to lightning
protection and automotive electrical and ignition systems. The
resistance material of the varistor is a semiconductor, so it is a
kind of semiconductor resistance. At present, a large number of
'zinc oxide' (ZnO) varistors are used, and their main materials are
composed of a divalent element (Zn) and a hexavalent element oxygen
(O). Therefore, from the material point of view, the zinc oxide
varistor is a "II-VI oxide semiconductor".
The application of varistors in automobiles can not only protect
automobiles, but also improve automobile manufacturing technology
and performance. SPD varistor manufacturers believe that rheostats
can also protect the voltage and suppress the overvoltage of
electronic ignition. When the ignition system is in normal working
condition, the ignition ring will generate counter electromotive
force. If the voltage across the secondary L2 calculated by the
turns ratio exceeds 20kV, the high voltage will cause instantaneous
breakdown of the spark plug, and the ignition will start normally.
However, if the ignition system fails and the ignition is not
normal, the induced voltage will cause a high overvoltage at the
primary end of the ignition system, thereby shortening the life. By
applying varistors and directly connecting varistors at both ends
of the composite tube, it is possible to protect the ignition
system, suppress overvoltage, and protect the automotive electrical
system.

Application
1. Varistor voltage: refers to the voltage value across the
varistor at a specified temperature and DC (generally 1mA or
0.1mA). Recorded as V1mA or V0.1mAo
2. Maximum continuous voltage: refers to the maximum effective
value of sinusoidal AC voltage or the maximum DC voltage value that
can be continuously applied to both ends of the varistor for a long
time under the specified ambient temperature
3. Limiting voltage: refers to the maximum peak voltage at both
ends of the varistor when a specified surge current (8,20μs) passes
through it.
4. Rated power: refers to the maximum average impact power that can
be applied to the varistor under the specified ambient temperature.
5. Maximum energy: the maximum impact energy that can be applied to
the varistor under the condition that the varistor voltage does not
change more than ±10% and the impulse current waveform is 10,
1000μs or 2ms.
6. Current capacity (maximum inrush current)
