The F1B1-303010/303012/303015 is an unshielded surface-mount power inductor in a 3.0 × 3.0 mm footprint at 1.0 mm to 1.5 mm height. Open construction enables higher saturation current ratings than shielded parts of the same size at lower cost, making these parts suited for general-purpose power chokes, DC-DC output filtering, and low-power circuit applications where placement away from sensitive signals is acceptable.
