The document describes an SMT power inductor called SIHM44, which features low profile, high energy storage, and low DC resistance. The inductor is suitable for power source circuits, DC-DC converters, and DC-AC inverters.
The SIHM44 series is a surface‑mount power inductor with a low profile of 2.9 mm maximum height, unshielded construction, and self‑lead design for high‑density mounting. It is intended for use in power‑source circuits, DC‑DC converters, and DC‑AC inverter applications, and can be supplied in embossed carrier‑tape packaging.\n\nMechanical dimensions are specified as a maximum height of 2.9 mm, with recommended pad sizes listed. Electrical characteristics include a range of inductance values from 0.9 µH to 100 µH, rated currents for each value, and a test condition of 100 kHz at 0.1 V measured at 29 °C. The device operates from –20 °C to 105 °C.
