LITTELFUSE Resettable PPTC Fuse, 2920L Series, 5s - 24V 2A 4A

The LITTELFUSE Resettable PPTC Fuse from the PolySwitch 2920L Series is a state-of-the-art, self-recovering overcurrent protection component designed for modern electronic circuits. Also known as a polymeric positive temperature coefficient (PPTC) device, this fuse automatically resets after the fault condition is cleared and the power is cycled, eliminating the need for manual replacement. This makes it an ideal and cost-effective solution for protecting sensitive circuitry in a wide range of applications.

Featuring a robust 2920 case style (equivalent to the 7351 metric package), this compact fuse provides reliable performance in a small footprint. It offers a voltage rating of 16VDC, with a holding current of 5A and a trip current of 10A. The device is engineered to trip within 5 seconds under overload conditions, swiftly interrupting excessive current to prevent damage to downstream components. With a maximum current rating of 40A, it can handle significant inrush currents while maintaining stable operation.

Constructed for resilience, this PPTC fuse operates reliably across a broad temperature range from -40°C to +85°C, making it suitable for use in harsh environmental conditions, including automotive and industrial settings. Its resettable functionality enhances product longevity and reduces maintenance costs, providing dependable circuit protection that engineers and designers can trust. This fuse is an essential component for safeguarding power supplies, battery packs, motors, and other critical electronic assets from overcurrent events.
