LITTELFUSE PolySwitch 1812L Resettable PPTC Fuse, 16V DC, 2A

The LITTELFUSE PolySwitch 1812L Series Resettable PPTC Fuse provides reliable overcurrent protection for electronic circuits. Designed in a compact 1812 (4532 Metric) case style, this polymeric positive temperature coefficient device helps protect sensitive components from fault conditions.

Operating at a voltage rating of 16V DC, the fuse features a holding current of 2A and a trip current of 3.5A. When an overcurrent event occurs, the device trips within 2 seconds, interrupting the fault current and safeguarding the circuit. Once the fault is removed and the power is cycled, the fuse resets itself, ensuring long-term operational efficiency without the need for replacement.

With a maximum current rating of 100A, this resettable fuse is suitable for a variety of demanding applications. It operates reliably within a broad temperature range from -40°C to 85°C, making it suitable for diverse environmental conditions.
