Gowanda’s 121KM5002SM is a wirewound toroidal inductor from the KMSM series, designed for high reliability in electronic applications. This component features a compact size with dimensions of 23.88 × 23.88 × 12.95 mm and weighs 14.5 grams. It is surface mount technology (SMT) compatible and is classified under the COTS+ application grade, ensuring suitability for commercial off-the-shelf applications with enhanced performance. The inductor offers an inductance of 50 µH, a direct current resistance (DCR) of 0.03 Ω, and a self-resonant frequency (SRF) of 4 MHz. It supports a current rating of 4.77 A DC, with incremental current levels of 2300 mA DC for a 10% inductance change and 4000 mA DC for a 20% change. The component has a tolerance of ±10% and features leaded terminations with a Sn63Pb37 finish. It operates efficiently across a wide temperature range from -55°C to +130°C and has a moisture sensitivity level (MSL) of 1, making it suitable for various demanding environments. The inductor is available in tape and reel packaging for ease of handling and installation.
