Chip Varistor

Achieve electrostatic protection excellent effect by ceramics materials and process technology of its own.
Alternate of the Zener diode is easy, and contribute to the size and weight of the applications.
The wide product line up of the laminate structure, and adaptable to a wide range of applications to high-speed signal lines from the power supply.


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.
