Introduction

A varistor has the volt-ampere characteristics in which current suddenly starts to flow through the device at a certain voltage. The varistors are used to protect components in electronic and electric circuits from overvoltage. PULSE ABSORPTION BY VARISTOR Thus, the circuit can be protected from being damaged by pulse voltages as long as it has withstand voltage larger than the maximum limit voltage. Owing to the characteristic, the varistors are extremely effective as protecting devices of electronic and electric equipment by absorption of abnormal voltages and lightening pulses.
