The 30R400UF is a radial leaded polymeric PTC resettable fuse from Littelfuse, part of the 30R Series. It holds 4A at 20°C still air without tripping and trips at a minimum of 8A. With a maximum voltage rating of 30V DC and a maximum fault current of 40A, it provides reliable overcurrent protection for low voltage applications. The device has a typical power dissipation of 2.5W in tripped state and a maximum time-to-trip of 12.7 seconds at 20A. Initial resistance is as low as 10 mΩ and up to 50 mΩ post-trip. Operating temperature ranges from -40°C to 85°C. The component measures 14.00mm x 3.00mm x 22.00mm with 5.10mm lead spacing and is through-hole mounted in a radial disc package. It is RoHS compliant, lead-free, and halogen-free. Common applications include USB hubs and ports, computer peripherals, motor protection, general electronics, and automotive low voltage circuits.
