The F1C2-0606 steps up to a 6.6 × 6.4 mm footprint with heights of 3.1 mm, 5.0 mm, and 6.0 mm, handling higher saturation currents than the 0505 with the same flat-wire T-core construction. Reduced AC losses and stable inductance under transients suit it for high-power DC-DC output chokes, server VRM stages, and industrial power filtering beyond the 0505 current capacity.
