808 Series - 250 VAC/450 VDC Fast-Acting TE5 Subminiature Fuse

Brand: Littelfuse, Inc

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.
