High Surge Varistor

- Sep 28, 2017 -

Flux is the peak current that represents the application of a specified pulsed current (8/20μs) waveform. Surge environment parameters include maximum surge current IPM (or Max surge voltage VPM and surge source impedance zo), surge pulse width tt, the minimum interval TM of adjacent two surges, and the total number of surge pulses in the pressure-sensitive resistor during the predetermined working life period. The pressure-sensitive resistor has larger flow capacity but smaller than gas discharge tube.
