0603L Resettable Fuses

Littelfuse 0603L Resettable Fuses provide surface mount overcurrent protection for applications with premium space and resettable protection is desired. These Polymeric Positive Temperature Coefficient (PPTC) devices feature low resistance, low profile, and fast response to fault currents. The 0603L resettable fuses include a compact design that saves board space and compatible with high-temperature solders. These fuses operate at -40°C to +85°C temperature range and 0.5W power dissipation. Typical applications include USB peripherals, disk drives, CD-ROMs, game console port protection, and PDAs / digital cameras.
