Miniature AC Varistor – MAV Low Power AC and Low Capacitance DC 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. Low capacitance makes these parts useful also for higher DC voltage data lines and other capacitance sensitive applications.
