1 A fast blow, 32 V DC, 1206 SMT fuse
F1206A1R00FWTR is a 1 A rated, fast blow surface-mount fuse from the KYOCERA AVX Accu-Guard® series, housed in a standard 1206 (3216 metric) package. It is designed for overcurrent protection on DC power rails up to 32 V, with a breaking capacity of 50 A at rated voltage. The fast blow response time, combined with a low melting I²t of 0.005, means this fuse clears quickly on overcurrent events — suited for protecting sensitive loads that cannot tolerate sustained fault energy.
DC cold resistance and operating temperature range
DC cold resistance is 0.18 Ohms, which sets the voltage drop and self-heating under normal load — at 1 A the drop is 0.18 V, negligible for most 3.3 V or 5 V rails.
Active production, Tape & Reel supply
cUL, UL approval — regulatory fit
The fuse is approved by cUL and UL, satisfying North American safety agency requirements for end-equipment certification. This listing is a common gate for telecom, industrial control, and consumer power supplies.
