Introduction
Multi layer chip varistors(MLV) have good
nonlinear voltage-current characteristics and
high surge capability. They also have fast-
response characteristics in several hundred pico
second level. They are very suitable and widely
used for the problems of transient over-voltage
protection caused by ESD(Electrostatic
Discharge).
