MF-R005-0 is a radial leaded PTC resettable fuse from Bourns designed to protect low voltage power supplies and loads in electronic circuits. The device features a maximum voltage rating of 60 V and maximum current of 40 A, with a hold current (Ihold) of 0.05 A and trip current (Itrip) of 0.10 A at 23°C. It exhibits an initial resistance of 7.3–11.1 O and a post-trip resistance of 22.0 O maximum, with a maximum time to trip of 5.0 seconds at 23°C. The component is constructed with cured, flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements and is RoHS compliant and halogen-free. Typical applications include computers, peripherals, general electronics, and automotive systems where overcurrent protection is required.
