SKOFF electrical components Germany SKOFF model SKOFF price

SKOFF electrical component is a resistive device with nonlinear voltage-current characteristics, mainly used for voltage clamping when the circuit is subjected to overvoltage, absorbing excess current to protect sensitive devices. The resistive body material of the varistor is a semiconductor, so it is a type of semiconductor resistor. The currently widely used "zinc oxide" varistor has a main body composed of divalent element zinc and hexavalent element oxygen. Therefore, from a material perspective, the zinc oxide varistor is a "II-VI group oxide semiconductor". In Taiwan, China, varistors
