The 0466004.NR is a 4A surface mount Very Fast-acting Fuse with advanced high temperature substrate body, 100% tin over nickel over copper terminations and conformal element cover coat. This is a small (1206 size) thin-film device designed for secondary protection of circuits used in space constrained applications such as hand-held electronic devices. It is compatible with lead-free solders and higher temperature profiles. It features low profile for height sensitive applications, flat top surface for pick-and-place operations. The element-covering material is resistant to industry standard cleaning operations.
