040KM1503SM

Gowanda’s 040KM1503SM 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 150 µH, a direct current resistance (DCR) of 0.19 Ω, and a self-resonant frequency (SRF) of 3.5 MHz. It supports a current rating of 1.45 A DC, with incremental current levels of 330 mA DC for a 10% change and 600 mA DC for a 20% change. The inductor features a tolerance of ±10% and uses lead-based (Pb) termination with a Sn63Pb37 finish. It operates efficiently across a wide temperature range from -55°C to +130°C, has a moisture sensitivity level (MSL) of 1, and is available in tape and reel (T&R) packaging for convenient handling and assembly.
