What is the Multilayer Chip Varistor?

Varistor stands for Variable Resistor

It’s a voltage nonlinear resistor/voltage-dependent resistor.

It is an element that changes its resistance value depending on applied voltage.

This is the ceramic electronic component the character of which is used to protect electronic devices from the abnormal voltage, such as lightning surge and static electricity.
