SMD0805 Series PPTC Resettable Fuse | Compact SMD Overcurrent Protection for Portable and High-Speed Circuits
The SMD0805 Series PPTC resettable fuse is built with 0805 (2012 metric) packaging for space-constrained, high-density PCBs. Utilizing PPTC polymeric technology, the device reacts quickly to overcurrent or short circuits, transitioning to a high-resistance state and automatically resetting after the fault is cleared. Typical hold currents range from 100mA to 1.1A, with operating voltages up to 60V. Ideal for USB/HDMI/DisplayPort interfaces, lithium battery packs, RF modules, touchscreens, TWS earbuds, and other portable electronics.
