MF-R025-2 is a radial-leaded PTC resettable fuse designed for low-voltage power supply protection in consumer electronics and general applications. It features a maximum voltage rating of 60 V and a maximum current rating of 40 A, with a hold current (Ihold) of 0.25 A and a trip current (Itrip) of 1.00 A at 23°C. The device has an initial resistance of 1.95 O and a post-trip resistance of 3.00 O maximum, with a maximum time to trip of 2.5 seconds at 23°C. Constructed with flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements, the MF-R025-2 is RoHS compliant and halogen-free, making it suitable for computers, peripherals, and general electronics where automatic circuit protection and resettability are required.
