The RUEF300 from TE Connectivity is a radial leaded PolySwitch resettable device designed for overcurrent protection. It features a fast trip time, low resistance, and a hold current of 3A at room temperature, with a maximum voltage rating of 30V and maximum current of 100A. The device trips at approximately 6A under room temperature conditions and has a maximum resistance of 0.08 ohms at 20°C one hour post-trip. It operates within a temperature range of -40°C to 85°C and is made with UL94 V-0 flame retardant epoxy polymer insulation. Suitable for safety, industrial, and portable device applications, it provides enhanced design flexibility and is compatible with high-volume electronics assembly. Users should note that operation in circuits with large inductance can generate voltages above the rated voltage, and the device is intended for protection against overcurrent or overtemperature faults, not for repeated fault conditions or prolonged trips.
