Brochure

The Bourns® GMOV™ component protection characteristics
are dened by Front Level Protection (V
fp
) and Clamping
Voltage Level (V
c
). V
fp
is measured with 10 % of peak current
in accordance with IEC 61051-1. It should be noted that V
fp
is
a very short duration event, lasting less than 0.3 µs.
The V
fp
represents the short time it takes for the GDT to turn
on. V
c
is dened as the clamping voltage level of the GMOV™
component which is the total of the MOV clamping voltage
and the on-state arc voltage of the GDT. V
c
occurs after the
GMOV™ component has transitioned into is its fully on-state.
