Varistor

- Low Capacitance Varistor
- Hybrid Varistor
- Multilayer Varistor
- Array Varistor
- Array Filter Varistor

Application
* IC and Transistor Protection
* Telecommunication Transient Protection
* LCD Module Protection Circuit
* USB, IEEE 1394 data line protection
* Protection Circuit Module [Li ion and Li Polymer 2nd Battery], etc.

Features
* Main Composition
  - Ceramic material : ZnO + additives
  - Internal Electrode : Pd, Ag-Pd, etc.
* Semi-conductive property
  - It is a insulator under a certain voltage level but the varistor
    becomes a low ohmic conductor within 0.5 ns for the duration of the over-voltage.

Definition
Varistor is variable resistance device which changes with the applied voltage.
