MF-R075 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 0.75 A and trip current (Itrip) of 1.50 A at 23°C. The device exhibits an initial resistance of 0.40 O and a post-trip resistance of 0.60 O maximum, with a maximum time to trip of 3.75 seconds and typical tripped power dissipation of 0.90 W. Constructed with flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements, the MF-R075 is RoHS compliant and halogen-free, making it suitable for protection in computers, peripherals, and general electronics where automatic circuit protection and self-recovery are required.
