Description
The multilayer chip varistor is a nonlinear resistive element containing zinc oxide (ZnO) as a main ingredient, which is newly developed for protection against surge voltage, noise, and other abnormal voltages.
Unlike conventional varistors, the maximum peak current and nonlinear coefficient are very large, and the resistance is very high under a certain critical voltage, hardly allowing the current to flow. When the critical voltage is exceeded, the resistance drops abruptly, allowing a large current to flow.
Such properties cause a dramatic effect as a protective element for electric and electronic equipment, absorbing abnormal voltages and lightning surge.
