RXEF010 0.1A Resettable Fuse – PPTC Polyfuse – 60V Radial – Littelfuse

The RXEF010 is a compact PPTC resettable fuse (polyfuse) designed to provide reliable overcurrent protection in low-power electronic circuits. Manufactured by trusted brands such as Littelfuse and Raychem, this radial-leaded PolySwitch device automatically resets after a fault condition is removed, eliminating the need for fuse replacement.

With a hold current of 0.1A and a trip current of 0.2A, the RXEF010 is ideal for sensitive circuitry requiring precise and fast protection. It supports up to 60V DC and can withstand surge currents up to 40A, offering robust performance in demanding applications. Typical trip time is 4 seconds at 1A, ensuring dependable response during overloads.

Engineered for long-term reliability, it operates across a wide –40°C to +85°C temperature range and carries safety approvals from UL, CSA, TÜV, and CQC. Common uses include telecom equipment, sensors, battery protection, safety circuits, and consumer electronics.
