Gowanda’s 121KM1003HMLF is a horizontally mounted, high-efficiency standoff toroidal choke designed for superior performance in demanding applications. With a compact size of 22.86 × 22.86 × 12.7 mm and a weight of 12 grams, this component is part of the KMHM series and is suitable for surface mount technology (SMT). It is crafted to meet COTS+ application grade standards, offering an inductance of 100 µH, a direct current resistance (DCR) of 0.065 Ω, and a self-resonant frequency (SRF) of 1.5 MHz. The choke 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 features a tolerance of ±10% and is compliant with RoHS standards, utilizing a Sn/Cu termination finish. The component operates efficiently across a wide temperature range from -55°C to +130°C, has a moisture sensitivity level (MSL) of 1, and is available in bulk packaging.
