Gowanda’s 121KM2503HC is a high-quality, reliable horizontal mount potted toroidal inductor, designed for demanding applications. Weighing 16 grams and measuring 24.13 × 24.13 × 13.97 mm, this inductor is part of the KMHC series and features through-hole technology (THT) for secure mounting. It is suitable for COTS+ application grades, offering an inductance of 250 µH with a direct current resistance (DCR) of 0.16 Ω and a self-resonant frequency (SRF) of 0.9 MHz. The inductor supports a current rating of 2.07 A DC, with incremental current limits of 900 mA DC for a 10% change and 1700 mA DC for a 20% change. It maintains a tolerance of ±10% and is RoHS compliant with a Sn/Cu termination finish. The 121KM2503HC operates effectively within a temperature range of -55°C to +130°C, has a moisture sensitivity level (MSL) of 1, and is available in bulk packaging.
