Board-mount fuse for 63 V DC rails
The F1206B1R00FWTR is a 1 A fast-blow fuse from the Accu-Guard® II series, designed for surface-mount board-level overcurrent protection on 63 V DC supplies. Its 1206 (3216 metric) footprint fits standard pick-and-place assembly, and the 50 A breaking capacity at rated voltage means it can safely interrupt a hard short without rupturing.
Fast-blow response and low energy let-through
With a melting I²t of 0.003, this fuse clears quickly on moderate overcurrents, limiting the energy delivered to downstream components during a fault. The 0.18 Ohm cold DC resistance keeps voltage drop low at rated current, which matters for tight-regulation rails.
