Gowanda’s 121KM7502H is a high-quality horizontal open construction toroidal inductor, designed for reliable performance in demanding applications. Weighing 11 grams and measuring 20.83 × 20.83 × 10.16 mm, this component is part of the KM series and features through-hole technology (THT) for mounting. It is classified under the COTS+ application grade, ensuring suitability for commercial off-the-shelf applications with enhanced reliability. The inductor offers an inductance of 75 µH, a direct current resistance (DCR) of 0.045 Ω, and a self-resonant frequency (SRF) of 3 MHz. It supports a current rating of 3.9 A DC, with incremental current levels of 1800 mA DC for a 10% inductance change and 3100 mA DC for a 20% change. The component has a tolerance of ±10% and features Pb termination with a Sn63Pb37 finish. It operates efficiently across a temperature range of -55°C to +130°C, has a moisture sensitivity level (MSL) of 1, and is available in bulk packaging.
