Small Volume SMD MOV Varistor Quick Response For Control Circuit Boards Power Systems
Quick Response Small Volume SMD MOV Varistor For Control Circuit Boards Power Systems
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
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.
