The Littelfuse 40008000000 is a TE5 series time-lag (slow blow) fuse designed for board mount applications. It is rated for 800mA at 250VAC with a breaking capacity of 50A. Key electrical characteristics include a melting I²t of 3.33 A²s (maximum at 10×IN), nominal cold resistance of 0.092Ω, and maximum power dissipation of 300mW at rated current. The slow blow response makes it suitable for circuits with inrush currents, such as power supplies and IC chip protection.
The fuse is housed in a radial box package with dimensions 8.50mm x 4.00mm x 8.00mm and features radial leads for through hole mounting. It is RoHS compliant, halogen free, and lead free as verified by the datasheet. The operating temperature range is -40°C to 85°C.
Note: The voltage rating of 250V in the product data conflicts with the datasheet for the 399 series which specifies 65V. Verification with the manufacturer is recommended before use in 250V applications.
