MF-R250-0-10 is a radial leaded PTC resettable fuse designed for automatic circuit protection in low-voltage power supplies and general electronics applications. It features a maximum voltage rating of 30 V and a maximum current rating of 40 A, with a hold current (Ihold) of 2.5 A and a trip current (Itrip) of 5.0 A at 23°C. The device exhibits an initial resistance of 0.048 O at 23°C and a post-trip resistance of 0.07 O maximum, with a maximum time to trip of 10.3 seconds. The component is constructed with flame-retardant epoxy polymer insulation meeting UL 94V-0 requirements, is RoHS compliant and halogen-free, and operates reliably across a temperature range of -40°C to +85°C. This resettable fuse is ideal for protecting circuits in computers, peripherals, and general electronic equipment where automatic recovery after fault conditions is desired.
