Gowanda’s 121KM1503SM is a high-quality wirewound toroidal inductor designed for demanding applications. This component, part of the KMSM series, features a compact size with dimensions of 23.88 × 23.88 × 12.95 mm and a weight of 14.5 grams. It is suitable for surface mount technology (SMT) and is classified under the COTS+ application grade, ensuring reliability in commercial off-the-shelf applications. The inductor offers an inductance of 150 µH with a direct current resistance (DCR) of 0.095 Ω and a self-resonant frequency (SRF) of 1.5 MHz. It supports a current rating of 2.68 A DC, with incremental current limits of 1300 mA DC for a 10% inductance change and 2200 mA DC for a 20% change. The component has a tolerance of ±10% and features lead (Pb) termination with a Sn63Pb37 finish. It operates efficiently across a wide temperature range from -55°C to +130°C and is rated at moisture sensitivity level (MSL) 1, making it suitable for various environmental conditions. The inductor is packaged in tape and reel (T&R) format for ease of handling and assembly.
