The RXEF090 is a polymeric Positive Temperature Coefficient (PTC) resettable fuse from Littelfuse Inc. It is designed to provide overcurrent protection in a wide range of electronic circuits. With a hold current of 900 mA and a maximum voltage of 72 V, it is suitable for low-power applications. The device has an initial resistance of 470 mΩ and a typical time to trip of 7.2 seconds at specified fault conditions.
This PTC fuse features a radial leaded disc package with a diameter of 11.20 mm and a thickness of 3.00 mm. The seated height is 15.80 mm with a lead spacing of 5.05 mm. The operating temperature range spans from -40°C to 85°C, allowing use in harsh environments.
Typical applications include overcurrent protection in power supplies, battery chargers, and consumer electronics. The polymeric PTC material ensures resettable protection, reducing the need for fuse replacement. The through-hole mounting offers reliable mechanical bonding for PCB assembly.
