3D-plastic Hans Kintra GmbH electrical components Germany 3D-plastic Hans Kintra GmbH model 3D-plastic Hans Kintra GmbH price

3D-plastic Hans Kintra GmbH 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 resistor body material of the varistor is 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-
