121KM1003HC

Gowanda’s 121KM1003HC is a high-quality horizontal mount potted toroidal inductor, designed for reliability and performance in demanding applications. Weighing 16 grams and measuring 24.13 × 24.13 × 13.97 mm, this component is part of the KMHC series and features through-hole technology (THT) for secure mounting. It is suitable for COTS+ grade applications, offering an inductance of 100 µH with a direct current resistance (DCR) of 0.065 Ω and a self-resonant frequency (SRF) of 1.5 MHz. The inductor supports a current rating of 3.24 A DC, with incremental current levels of 1600 mA DC for a 10% inductance change and 2800 mA DC for a 20% change. It has a tolerance of ±10% and is RoHS compliant with a Sn/Cu termination finish. The 121KM1003HC operates efficiently across a wide temperature range from -55°C to +130°C and is available in bulk packaging with a moisture sensitivity level (MSL) of 1.
