The Bourns MOV-20D431K is a 20mm radial leaded metal oxide varistor (MOV) designed for overvoltage transient protection. It offers a varistor voltage of 430V typical at 1 mA DC, with a tolerance of ±10%. The device can handle a maximum continuous AC voltage of 275V and DC voltage of 350V.
Key electrical ratings include a peak surge current of 6.5 kA (8/20 µs, one time), maximum clamping voltage of 710V at 100A, and energy absorption capability of 190J. The response time is typically 25 ns, with a minimum of 10 ns. Capacitance is 1116 pF at 1 kHz.
The MOV operates over a temperature range of -40°C to 105°C and has a rated wattage of 1.00W. The varistor voltage temperature coefficient is 0.05 %/°C. The device is RoHS compliant and UL 1449 listed (file E313168).
The package is a through-hole Disc 20mm with straight or kinked lead styles available. It is suitable for power supply, industrial, and consumer electronics applications requiring surge protection.
