MF-RX014/250-2 is a telecom-grade PTC resettable fuse designed for fast-tripping protection in customer premise equipment and central office applications. It features a maximum operating voltage of 60 Vdc, maximum interrupt rating of 250 Vrms at 3.0 A, and a hold current of 0.145 A at 23°C. The device exhibits an initial resistance of 8.0 O (minimum) to 10.5 O (maximum) at 23°C, with a one-hour post-trip resistance of 16.0 O. Operating over a temperature range of -40°C to +85°C with a maximum device surface temperature of 125°C in the tripped state, this component is RoHS compliant and meets agency recognition standards. The MF-RX014/250-2 is ideal for protecting telecom infrastructure against overcurrent conditions while maintaining the ability to reset automatically after fault clearance, supporting compliance with ITU-T K.20/K.21/K.45 and Telcordia GR-1089-C standards.
