SMD MOV Varistor.pdf
Four characteristics of MOV varistors:
1. Protection characteristics
When the impulse strength (or impulse current Isp=Usp/Zs) of the
impulse source does not exceed the specified value, the clamping
voltage of the MOV is not allowed to exceed the impulse withstand
voltage of the protected electronic circuit.
2. Shock resistance
That is, the MOV varistor itself bears the rated impact current and
impact energy, including an average power when multiple impacts
occur in succession.
3. Life characteristics
There are two life characteristics here, one is the life of
continuous working voltage, that is, the varistor should be able to
work reliably for the set time under the set ambient temperature
and system voltage conditions. The second is the impact life, which
is the number of times it can withstand the set impact.
4. After the piezoresistor intervenes in the system, in addition to
the protective function of the "safety valve", it will also bring
about "secondary effects", which should not reduce the working
performance of the normal system.
Description:
SMD Varistor For ESD Protection has been developed to protect automotive
electronic circuits against transient overvoltages, such as
electrostatic discharges and surge
SMD Varistor Characteristic
SMD Varistor is a kind of the voltage sensitive resistor,
symmetrical volt-ampere characteristics, its value as the voltage
rises is nonlinear, when the voltage within a certain range to rise
further, the phenomenon of "short circuit" more intense.
