121KM5002V

Gowanda’s 121KM5002V is a high-quality, reliable vertical open construction toroidal inductor designed for demanding applications. Weighing 10 grams and measuring 20.83 × 20.83 × 10.16 mm, this component is part of the KM series and features through-hole technology (THT) for mounting. It is suitable for COTS+ application grades, offering an inductance of 50 µH with a direct current resistance (DCR) of 0.03 Ω and a self-resonant frequency (SRF) of 4 MHz. The inductor supports a current rating of 4.77 A DC, with incremental current limits of 2300 mA DC for a 10% inductance change and 4000 mA DC for a 20% change. It has a tolerance of ±10% and uses Pb termination with a Sn63Pb37 finish. The component operates efficiently across a temperature range of -55°C to +130°C, has a moisture sensitivity level (MSL) of 1, and is available in bulk packaging.
