V Series Metal Oxide Varistors Chemi-Con V Series Metal Oxide Varistors have a higher capability of surge currents and energy. These varistors feature low clamping voltage, high reliability, fast response, and excellent voltage non-linear coefficients. The V series varistors offer symmetrical V-I characteristics (no polarity), excellent temperature characteristics, and stable characteristics against repeated surges. These varistors comply with RoHS 2 and UL standards. The Chemi-Con TNR V series varistors protect electronic instruments from lightning surges and absorption of on-off surges from motors and relays.
