The main parameters and circuit applications of varistors.
2025-01-02
Introduction: Varistors are generally used in parallel in circuits. When the voltage across the resistor changes sharply, the resistor shorts out, causing the current fuse to blow, thus providing protection. Varistors are commonly used in circuits for over-voltage protection and voltage stabilization. Parameters to understand in circuit design: 1. Varistor voltage UN (U1mA): This is usually represented by the voltage across the varistor when a direct current of 1mA flows through it, indicating whether it is conducting. This voltage is referred to as the varistor voltage UN. The varistor voltage is also commonly denoted by the symbol U1mA. The error range for the varistor voltage is generally ±10%. In testing and practical use.
