The RXEF050 is a polymeric positive temperature coefficient (PTC) resettable fuse from Littelfuse Inc. It is designed for overcurrent protection in electronic circuits, automatically resetting after the fault is cleared. This device is rated for a maximum voltage of 72V and a hold current of 500mA. The initial resistance is 1.17Ω, and the typical trip time is 4 seconds at the specified fault current.
The RXEF050 comes in a through-hole radial disc package with dimensions of 7.90mm diameter and 3.00mm thickness, and a height of 13.70mm including leads. The lead spacing is 5.05mm (0.199 inches). It can operate over a temperature range of -40°C to 85°C.
This fuse is suitable for a variety of applications requiring resettable overcurrent protection, such as power supplies, battery chargers, and telecommunications equipment. Its polymeric construction provides low resistance during normal operation and rapid switching to a high-resistance state under fault conditions.
