Miniature AC Varistor – MAV
Low Power AC Circuit Protection
GENERAL DESCRIPTION
AVX Miniature AC Varistors are designed for use in low power
AC circuit protection. MAV series devices are an ideal
solution to transient suppression in LC resonant circuits
intended for signal & power transfer. The AVX part provides
low loss in the resonant circuit yet is able to clamp large
amounts of transients in a bi-directional manner.
The ability to handle large transients makes the MAV series
useful in low power AC circuit protection and the AEC Q200
qualification allows for use in automotive applications.
