Overview of RXEF050 by Littelfuse Inc.
The RXEF050 by Littelfuse Inc. is a PolySwitch resettable fuse, specifically designed for through-hole mounting with a radial lead configuration. This component is notable for its 0.5A holding current, a significant feature that enables it to protect against overcurrent situations without needing to be replaced. With a tripping current of 1A, it automatically resets after a fault condition is cleared, making it an ideal component for a wide variety of applications that demand reliable overcurrent protection with minimal downtime.
Part of the PolySwitch RXEF series, this resettable fuse boasts a voltage rating of 72Vdc, accommodating a broad spectrum of DC applications. It operates over a temperature range from -40°C to 85°C, ensuring reliable performance in environments subjected to temperature variations. The fuse’s time to trip is 4 seconds, featuring a maximum current rating of 40A, with lead spacing of 5.8mm. This component’s design includes a round fuse shape, aligning with the radial, through-hole mounting requirement. Additionally, ensuring compliance with environmental safety standards, the RXEF050 is both RoHS compliant and lead-free.
According to its Non-linear Resistors classification, further detailed attributes include a resistance range of 0.5-0.77 ohms at 20°C, denoting its highly sensitive response to overcurrent conditions within specified temperature parameters. The part’s packaging and terminations are also designed with reliability in mind, featuring a matte tin (Sn) terminal finish for improved solderability and corrosion resistance.
