The MF-USHT050KX-2 is a PTC resettable fuse designed for overcurrent protection in high-temperature environments. At 23°C, it has a hold current of 0.50 A, a trip current of 2.50 A, and a maximum operating voltage of 30 V. The device features a fast maximum time-to-trip of 0.1 seconds at 8.0 A and has an initial resistance between 0.30 Ω and 1.60 Ω. With an operating temperature range of -20 °C to +125 °C, it is well-suited for demanding applications. Common uses include the protection of automotive circuitry, such as engine control modules, and other electronic equipment requiring resettable fault protection at high operating temperatures.
