Gowanda’s 121KM1003SM is a high-quality wirewound toroidal inductor designed for demanding applications. With a weight of 14.5 grams and compact dimensions of 23.88 × 23.88 × 12.95 mm, it belongs to the KMSM series and is suitable for surface mount technology (SMT). This component is crafted for COTS+ application grade, offering an inductance of 100 µH and a direct current resistance (DCR) of 0.065 Ω. It features a self-resonant frequency (SRF) of 2 MHz and a current rating of 3.24 A DC. The inductor can handle incremental current levels of 1600 mA DC with a 10% inductance change and 2800 mA DC with a 20% change, maintaining a tolerance of ±10%. It is equipped with Pb termination type and Sn63Pb37 termination finish, operating efficiently within a temperature range of -55°C to +130°C. With a moisture sensitivity level (MSL) of 1, it is packaged in tape and reel (T&R) format for ease of use in automated assembly processes.
