AQxxC-01FTG Series
Description
RoHS
Pb
GREEN
The bidirectional AQxxC series is designed to replace
multilayer varistors (MLVs) in electronic equipment for low
speed and DC applications. It will protect any sensitive
equipment from damage due to electrostatic discharge
(ESD) and other transient events.
The AQxxC series can safely absorb repetitive ESD strikes
at ±30kV (contact discharge, IEC 61000-4-2) without
performance degradation and safely dissipate 30A (AQ05C)
of 8/20μs induced surge current (IEC 61000-4-5) with very
low clamping voltages.
