Overview of RUEF400 by Littelfuse Inc.
The RUEF400 by Littelfuse Inc. is a PTC (Positive Temperature Coefficient) resettable fuse designed for through-hole mounting with radial leads. It forms part of the Polyswitch Ruef series, known for their reliable protection in a variety of applications. This component is specified to operate at a voltage rating of 30Vdc, with a holding current of 4A and a tripping current of 8A. Its time to trip is specified to be 12.7 seconds, which indicates the time required for the fuse to respond to a fault condition. The RUEF400 can handle a maximum current of 100A and has a lead spacing of 5.8mm. It adheres to RoHS compliance, ensuring its suitability for use in environments that require lead-free components.
The resistor is housed in a rectangular package, with dimension specifications including a package height of 19.3 mm, length of 14 mm, and width of 3 mm. It is designed for through-hole mount applications and has two radial terminals with a wire terminal shape, finished with matte tin. The rated power dissipation for the RUEF400 is 2.5 W, and it operates within a resistance range of 0.05 ohms. Operating temperature ranges from -40 °C to 85 °C, making it suitable for a wide range of environments.
