121KM2503H

Gowanda’s 121KM2503H is a high-quality, reliable horizontal open construction toroidal inductor designed for demanding applications. Weighing 11 grams and measuring 21.59 × 21.59 × 10.16 mm, this inductor is part of the KM series and features through-hole technology (THT) for mounting. It is suitable for COTS+ grade applications, offering an inductance of 250 µH, a direct current resistance (DCR) of 0.16 Ω, and a self-resonant frequency (SRF) of 1 MHz. The inductor supports a current rating of 2.07 A DC, with incremental current limits of 900 mA DC at a 10% change and 1700 mA DC at a 20% change. It has a tolerance of ±10% and uses lead (Pb) termination with a Sn63Pb37 finish. The operating temperature range is from -55°C to +130°C, with a moisture sensitivity level (MSL) of 1, and it is available in bulk packaging.
