MOV-10D431KTR is a 10 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 430 V at 1 mA DC, with a maximum continuous voltage rating of 275 V rms and 350 V dc. The varistor exhibits high current handling capability with a maximum peak current of 710 A (8/20 µs), maximum energy absorption of 2500 J per surge, and a fast response time of 10–25 ns. It operates reliably across a temperature range of -40°C to +105°C and is RoHS compliant with UL 1449 and ITU-T K.20, K.21, K.45 agency listings. These characteristics make it ideal for protecting power supplies, power systems, line voltage circuits, telecom systems, and white goods/appliances from transient overvoltage events.
