MOV-07D391KTR is a 7 mm radial leaded metal oxide varistor designed to protect against overvoltage transients such as lightning, power contact, and power induction. This device features a nominal varistor voltage of 390 V with a maximum continuous voltage rating of 250 V r.m.s. (320 V d.c.), and delivers a maximum peak current of 25 A at 8/20 µs pulse with a maximum energy absorption of 1200 J. The varistor exhibits fast response times of 10–25 ns and operates reliably over a temperature range of -40°C to +105°C with a varistor voltage temperature coefficient of 0.1 %/°C. The device is housed in an RoHS-compliant molded radial package with 100% Sn plating on terminations, making it suitable for power supplies, power systems, line voltage applications, telecom systems, and white goods/appliances.
