Gowanda’s 040KM2503SM is a high-quality wirewound toroidal inductor designed for demanding applications. Weighing 3.5 grams and measuring 14.35 × 14.22 × 9.14 mm, this inductor is part of the KMSM series and features surface mount technology (SMT) for easy integration. It is classified as COTS+ grade, ensuring reliability in commercial off-the-shelf applications. With an inductance of 250 µH, a direct current resistance (DCR) of 0.36 Ω, and a self-resonant frequency (SRF) of 2.5 MHz, it supports a current rating of 1.05 A DC. The inductor can handle incremental current levels of 250 mA DC with a 10% change and 480 mA DC with a 20% change, maintaining a tolerance of ±10%. It features lead (Pb) termination with a Sn63Pb37 finish, operates within a temperature range of -55°C to +130°C, and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R), it is ideal for efficient manufacturing processes.
