Miniature AC Varistor
__________________________________________________________________________________________
AVX introduces Miniature AC varistors for use in automotive applications.
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 bidirectional manner.
The ability to handle large transients makes the MAV series useful in low
power AC circuit protection as well. Applications including: AC sampling
circuitry, transformer secondaries, and GFI modules.
