Littelfuse 1206L400SLWR Resettable PTC Device

Littelfuse LoRho Surface Mount PPTC devices provide overcurrent protection with ultra-low internal resistance and voltage drop. This series allows for a higher hold current in a smaller profile compared to standard PPTCs. They are UL recognized and TUV approved, available in sizes from 0402 to 2920, and suitable for applications including USB peripherals, Li-ion battery packs, smartphones, and tablet PCs. The 0402 size is the smallest surface mounted PPTC device available. Users should independently assess suitability for each application and avoid exceeding maximum ratings to prevent damage.
