The Littelfuse RXEF185 is a polymeric PTC resettable fuse designed for overcurrent protection in electronic circuits. It features a hold current of 1.85 A and a maximum voltage rating of 72 V. The time to trip is 12.6 seconds, and the initial resistance is 190 mΩ.
This component uses polymeric PTC technology, which allows it to automatically reset after a fault condition is cleared. It is housed in a radial, disc package with through-hole mounting. Key mechanical specifications include a lead spacing of 5.05 mm, a diameter of 0.689 inches (17.50 mm), a thickness of 0.118 inches (3.00 mm), and a seated height of 22.40 mm.
The RXEF185 operates over a temperature range of -40°C to 85°C, making it suitable for a variety of environments. It is commonly used in power supplies, battery chargers, and other low-voltage applications requiring resettable overcurrent protection. The part is listed as RoHS3 compliant and REACH unaffected, though these compliance claims are unverified.
