040KM1003SM

Gowanda’s 040KM1003SM 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 100 µH, a direct current resistance (DCR) of 0.155 Ω, and a self-resonant frequency (SRF) of 6 MHz. It supports a current rating of 1.6 A DC, with incremental current levels (Δ10% mA DC) at 400 and (Δ20% mA DC) at 760. The inductor features a tolerance of ±10%, a lead-based termination type with a Sn63Pb37 finish, and operates efficiently within a temperature range of -55°C to +130°C. It is rated at moisture sensitivity level (MSL) 1 and is available in tape and reel (T&R) packaging for ease of use in automated assembly processes.
