MF-R010-AP is a radial-leaded PTC resettable fuse designed for overcurrent protection in low-voltage power supplies and electronic circuits. It features a maximum voltage rating of 60 V and maximum current rating of 40 A, with a hold current (Ihold) of 0.10 A and trip current (Itrip) range of 2.50 to 4.50 A at 23°C. The device exhibits an initial resistance of 2.50 to 4.50 O and a post-trip resistance of 7.50 O maximum, with a maximum time to trip of 4.0 seconds. The component is constructed with cured, flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements, is RoHS compliant and halogen-free, and features Sn/NiCu plated leads. It is commonly used in computers, peripherals, general electronics, and automotive applications where automatic resettable protection is required.
