The MF-R800 is a radial leaded PTC resettable fuse designed to protect low-voltage power supplies and electronic loads from overcurrent conditions. It features a maximum voltage rating of 30 V, a hold current of 8.0 A, and a trip current of 16.0 A, with an initial resistance of 0.02 O at 23°C and a post-trip resistance of 0.03 O maximum. The device exhibits a maximum time to trip of 18.8 seconds at 23°C with a typical tripped power dissipation of 4.00 W. Constructed with flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements, the MF-R800 is RoHS compliant and halogen-free, making it suitable for computers, peripherals, and general electronics applications where automatic overcurrent protection and automatic recovery are required.
