Gowanda’s 040KM2503SMLF 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 250 µH and a direct current resistance (DCR) of 0.36 Ω. It features a self-resonant frequency (SRF) of 2.5 MHz and a current rating of 1.05 A DC. The inductor can handle incremental current levels with a 10% inductance change at 250 mA DC and a 20% change at 480 mA DC, maintaining a tolerance of ±10%. It is RoHS compliant with a Sn/Cu termination finish, and it operates efficiently across a wide temperature range from -55°C to +130°C. The component 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.
