The F1C1-1412 uses a T-core iron-powder alloy structure in a fully shielded 1.4 × 1.2 mm body at 0.8 mm height. The T-core geometry improves efficiency over conventional winding designs, and the ultra-low profile suits server VRM and PPM modules, mobile handsets, and LCD display driver boards where height is the primary constraint and shielding protects adjacent signal circuitry.
