Gowanda’s 040KM7502SM is a high-quality wirewound toroidal inductor designed for demanding applications. With a weight of 3.5 grams and compact dimensions of 14.35 × 14.22 × 9.14 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 75 µH and a direct current resistance (DCR) of 0.14 Ω. It features a self-resonant frequency (SRF) of 9 MHz and a current rating of 1.69 A DC. The inductor can handle incremental current levels of 450 mA DC with a 10% inductance change and 860 mA DC with a 20% change, maintaining a tolerance of ±10%. It uses leaded (Pb) termination with a Sn63Pb37 finish and operates efficiently across 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) for ease of use in automated assembly processes.
