Littelfuse PolySwitch miniSMDC 12V DC 2.6A Resettable PPTC Fuse

The Littelfuse PolySwitch miniSMDC260F/12-2 is a 2.6A surface-mount resettable fuse (PPTC), engineered for compatibility with high-volume electronics assembly processes. Its compact, 1812 (4532 Metric) footprint makes it an ideal circuit protection solution for space-constrained, modern electronic designs, from consumer gadgets to automotive systems.

As a core component of the PolySwitch miniSMDC series, this device offers reliable overcurrent protection by rapidly transitioning to a high-resistance state when a fault current is detected, thereby limiting circuit current. Once the fault is cleared and power is cycled, the device automatically resets, restoring normal operation and eliminating the need for manual fuse replacement. This resettable functionality enhances product durability and reduces maintenance costs.

Key features and benefits include a fast time-to-trip for swift protection of sensitive components, a low initial resistance to minimise power loss and heat generation during normal operation, and a halogen-free construction for environmental compliance. The higher 12V DC voltage rating expands its usability into new and demanding applications across various industries.

Designed to assist in meeting stringent regulatory requirements, this PPTC fuse is a preferred protection method in computer peripherals, consumer electronics, communications networking, portable devices, and automotive electronics. Its robust performance across an operating temperature range of -40°C to 85°C ensures reliability in diverse and challenging environments.
