Gowanda’s 121KM2502SM 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 features surface mount technology (SMT) for easy integration. This inductor is classified as COTS+ application grade, offering an inductance of 25 µH and a low DC resistance of 0.017 Ω. It operates efficiently with a self-resonant frequency of 8 MHz and a current rating of 6.34 A DC. The component can handle incremental current changes of 3300 mA DC at a 10% inductance drop and 5700 mA DC at a 20% drop, with a tolerance of ±10%. It features lead (Pb) termination with a Sn63Pb37 finish and operates reliably across a wide temperature range of -55°C to +130°C. The inductor is rated at moisture sensitivity level 1 and is available in tape and reel packaging for convenient handling and assembly.
