MF-R030-2 is a radial leaded PTC resettable fuse designed for overcurrent protection in low voltage power supply applications. It features a hold current of 0.30 A, trip current of 0.60 A, and maximum voltage rating of 60 V with a maximum interrupt current of 40 A. The device has an initial resistance range of 0.76 to 1.36 Ohms at 23°C, with a maximum time to trip of 0.5 seconds and typical tripped power dissipation of 0.50 W. Operating over a temperature range of -40°C to +85°C, this RoHS compliant device is suitable for computers, peripherals, general electronics, and automotive applications where reliable, self-resetting overcurrent protection is required. The "-2" suffix indicates tape and reel packaging for automated assembly.
