Craig And Derricott electrical components Germany Craig And Derricott model Craig And Derricott price

Craig And Derricott 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 semiconductor, so it is a type of semiconductor resistor. The 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".
