DESCRIPTION

The MF-R250 is a radial-leaded PTC resettable fuse designed to protect low-voltage power supplies and loads in electronic equipment. It features a maximum voltage rating of 30 V and a maximum current rating of 40 A, with a hold current (Ihold) of 2.5 A and a trip current (Itrip) of 5.0 A at 23°C. The device exhibits an initial resistance of 0.048 O and a post-trip resistance of 0.07 O maximum, with a maximum time to trip of 10.3 seconds and typical tripped power dissipation of 1.20 W. Constructed with cured, flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements, the MF-R250 is RoHS compliant and halogen-free, making it suitable for computers, peripherals, and general electronics applications where reliable overcurrent protection is essential.
