The varistor has a large stray capacitance, when it is used in the protection of AC power system, it often forms a significant leakage current test in the normal start-up condition. For example, a varistor with a stray capacitance of 2000pf is placed in a 220 V / V / 50 Hz AC power system with a lea

1. Commonly used voltage-sensitive voltage, that is, dielectric strength or threshold voltage. It refers to the voltage value measured in many cases when the nominal voltage-sensitive voltage DC current is passed into the varistor. The varistor voltage limit of its product is allowed at approximatel

Nominal parameters of varistor: Varistors are represented by the letter "my", if J is added to the household, The letters W, G, P, L, H, Z, B, C, N, K are used for voltage stabilization, overvoltage protection, high frequency circuit, lightning protection, arc extinguishing, noise elimination, compe

Nowadays, the varistor occupies a high market share and occupies an important position in the electronic components. For us, when we choose the voltage, the higher the voltage is, the better? The first thing to understand is the principle and function of varistors. The voltage protection effect of a
