The F1C2-1111 spans heights from 3.1 mm to 10.0 mm over an 11.9 × 11.0 mm footprint, covering the widest inductance and current range in the F1C2 family. Flat wire limits skin-effect losses at higher frequencies, and the T-core iron-powder alloy construction maintains smooth inductance rolloff under transients. Suited for high-power DC-DC output stages, UPS input chokes, and industrial power conditioning.
