MF-R050-AP is a radial-leaded PTC resettable fuse designed for low-voltage power supply protection in consumer electronics and computing applications. It features a maximum voltage rating of 60 V and maximum current rating of 40 A, with a hold current (Ihold) of 0.5 A and trip current (Itrip) of 1.0 A at 23°C. The device exhibits an initial resistance of 0.77 O and a post-trip resistance of 1.17 O (maximum at 23°C), with a maximum time to trip of 4.0 seconds and typical tripped power dissipation of 0.75 W. Constructed with cured, flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements, the component is RoHS compliant and halogen-free. This resettable fuse is ideal for protecting circuits in computers, peripherals, and general electronics where automatic recovery after fault conditions is required.
