The Littelfuse RXEF050S is a polymeric PTC (Positive Temperature Coefficient) resettable fuse designed for overcurrent protection. With a hold current of 500 mA and a maximum voltage rating of 72V, it provides reliable circuit protection in a compact radial disc package.
This device features a low initial resistance of 1.17 ohms, ensuring minimal power loss under normal operating conditions. The time to trip at a typical fault is 4 seconds, allowing quick response to overcurrent events while minimizing nuisance trips.
The RXEF050S is suitable for a variety of applications including power supplies, industrial controls, and consumer electronics where resettable overcurrent protection is required. It operates over a temperature range of -40°C to 85°C, accommodating harsh environments.
The through-hole mounting and radial lead format with 5.05mm lead spacing simplifies integration into PCB designs. The package dimensions are 7.90mm diameter and 3.00mm thickness with a height of 13.70mm.
