Explanation

semiconductive ceramics with voltage and current nonlinearity (varistor effect). The applied voltage at both ends of the element is lower than a certain critical value, and the voltage sensitive element is in a high resistance state and its volt ampere characteristics are linear; When the applied voltage exceeds the critical value, its volt ampere characteristics will become transformation, and the voltage will increase slightly. The current suddenly increases by several orders of magnitude, known as the voltage sensitive effect. It has been widely used in power systems, electronic circuits, and general household electrical equipment, especially in overvoltage protection, high-energy wave absorption, and high-voltage voltage stabilization.
