Littelfuse lead-free SMD fuses trips at 0.2s

The 466 series of surface-mount fuses from Littelfuse can cut off current flow to a circuit in as little as 0.2s at 300 percent its rated current, and is targeted for use in surface-mount devices, PCs, and office equipment.

A part of the SlimLine portfolio, the fuses are lead-free and feature terminations that use copper, nickel, or tin, to comply with the requirements of Europe's Waste from Electrical and Electronic Equipment and the Japanese Electronics Industry Development Association. The fuses are claimed to withstand the higher 2600C soldering temperature required by lead-free wave and reflow soldering.

The devices are available with current ratings of 0.125A to 7A and a voltage rating of 24V to 125V, and can be used in either ac or dc circuits. They are packaged in standard 1206 casings with a 0.58mm profile.

Pricing for all amperage ratings are $0.25 for 10,000 piece quantities.
