The Bourns MF-RX014/250-0 is a polymeric PTC resettable fuse from the MF-RX/250 series, designed for telecom applications including customer premise equipment (CPE) and central office/telecom centers. It features a hold current of 145 mA, a maximum operating voltage of 60V DC, and an interrupt voltage rating of 250V. The device has a trip current of 280 mA and a maximum time to trip of 5 seconds at 1.0 A. Initial resistance ranges from 3 Ω to 6 Ω at 23°C, with a one-hour post-trip resistance of 14 Ω maximum. Tripped power dissipation is 1.0 W.
This PTC fuse is packaged in a radial leaded disc with through-hole mounting, lead spacing of 5.10 mm, and dimensions of 6.50 mm x 4.60 mm x 11.00 mm. It operates over a temperature range of -40°C to 85°C and is rated for a maximum interrupt current of 3 A. The device is RoHS3 compliant and carries cUL and TÜV agency recognitions.
Key specifications include fast trip time, binned resistance ranges, and suitability for overcurrent protection in telecom access equipment. The part is available in multiple resistance bin options (suffixes A, B, C, T, U) for design flexibility.
