The Littelfuse 808 Series TE5® fast acting subminiature fuse is rated at 250VAC/450VDC and is designed to protect components or internal circuits against overcurrent conditions, particularly in high voltage DC applications, such as DC power supplies. Its high interrupt rating/breaking capacity (up to 10kA@450VDC) ensures it will open safely under high fault currents. This low-profile, small-footprint subminiature fuse complements existing DC-rated cartridge fuse offerings from Littelfuse. This expanded selection gives circuit designers greater freedom to develop energy-efficient DC designs.
