2 A fast-blow fuse for board-level overcurrent protection
The F1206B2R00FWTR is a 2 A rated fast-blow surface-mount fuse from the KYOCERA AVX Accu-Guard® II series, housed in a standard 1206 (3216 metric) package. It is designed to protect downstream circuitry from overcurrent faults on 63 VDC or lower rails.
With a melting I²t of 0.03 A²s, this fuse offers low energy let-through — suitable for protecting sensitive ICs and modules where the downstream components have limited surge capability. The 0.08 Ω DC cold resistance keeps the voltage drop low at rated current.
Breaking capacity and approvals — design-in confidence
Rated breaking capacity of 50 A at 63 VDC ensures the fuse clears a hard short without arcing or casing rupture, within the typical fault current range of low-voltage DC supplies. cUL and UL recognition means this component can be used in UL-listed end products without additional fuse testing — a direct time-to-market advantage for safety-certified designs.
Temperature range and mounting — fits standard reflow profiles
KYOCERA AVX continues to manufacture this Accu-Guard® II series fuse, so multi-year BOM commitments are straightforward.
