The RXEF250K-2 is a polymeric PTC resettable fuse from Littelfuse Inc. It is designed for overcurrent protection and automatically resets after the fault is cleared. The device is rated for a maximum voltage of 72V and a hold current of 2.5A. Its typical initial resistance is 130 mΩ, and the time to trip is 15.6 seconds at rated conditions.
This fuse is housed in a radial, disc package with through-hole mounting. The lead spacing is 10.15mm (0.400"), and the seated height is 25.40mm (1.000"). The device diameter is 20.80mm with a thickness of 3.00mm. Operating temperature range is -40°C to 85°C.
Polymeric PTC fuses are ideal for applications requiring resettable overcurrent protection, such as power supplies, battery packs, and industrial controls. The radial package allows for easy insertion in PCB layouts. The straight lead style (may be formed) provides flexibility for mounting.
