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.
