Product details

750 mA fast blow SMD fuse for board-level protection

The F1206A0R75FWTR is a 750 mA fast blow surface mount fuse from the KYOCERA AVX Accu-Guard® series, housed in a standard 1206 (3216 metric) package. It is designed to clear a fault before downstream semiconductors or PCB traces suffer thermal damage, with a melting I²t of 0.003 A²s that coordinates with typical IC surge ratings.

Breaking capacity and voltage rating

Rated for 32 VDC, this fuse can safely interrupt a short-circuit current up to 50 A without arc-over or case rupture. The 0.25 Ohm cold resistance keeps voltage drop low at rated load — about 0.19 V at 750 mA — so it won't starve the load rail.

Frequently asked questions

What is the melting I²t of F1206A0R75FWTR and why does it matter?

The melting I²t is 0.003 A²s. This value determines the energy required to open the fuse, which is used to coordinate with the surge withstand rating of downstream semiconductors — a lower I²t protects more sensitive components but may nuisance-blow on brief inrush.

Is F1206A0R75FWTR RoHS compliant?

The evidence does not explicitly list RoHS compliance, but KYOCERA AVX Accu-Guard® fuses are typically RoHS-compliant. Verify the specific date code or lot certificate with your order.
