Capacitors have different roles in different applications. The protection of varistor is believed to be very clear to everyone, so this article will tell you about the state and function of varistor in different application applications, and follow the progress of editing into the topic of this article!
1) The varistor sensitive to voltage changes, in normal state, it exhibits a high impedance state. When the applied voltage exceeds the design value, it will exhibit a low impedance to release excessive voltage, which is used as the absorption of the surge voltage.
2) The varistor which exhibits different resistance values to the externally applied physical pressure, and is mainly used as a pressure sensor, such as an electronic scale.
The varistor in the circuit has three functions of overvoltage protection, lightning resistance requirements and safety test requirements. With the development of technology, the sales of varistor in recent years are also constantly rising. At the time of purchase, we must pay attention to the quality of the products and ensure the safe use of components.
