MF-R050 Resettable Fuse (PTC)

The MF-R050 is a Polymeric Positive Temperature Coefficient (PPTC) resettable fuse designed to protect circuits against overcurrent conditions. With a hold current of 0.5A, it automatically trips (increases resistance) when a fault occurs and resets itself once the power is removed and the device cools down. This eliminates the need to replace blown fuses, making it ideal for protecting USB ports and DC motors.
