Gowanda’s 121KM1503HMLF is a horizontally mounted, high-efficiency standoff toroidal choke designed for demanding applications. Weighing 12 grams and measuring 22.86 mm in both width and length with a height of 12.7 mm, this component is part of the KMHM series and is suitable for surface mount technology (SMT). It is crafted for COTS+ application grade, offering an inductance of 150 µH with a direct current resistance (DCR) of 0.095 Ω and a self-resonant frequency (SRF) of 1 MHz. The choke supports a current rating of 2.68 A DC, with incremental current limits of 1300 mA DC for a 10% change and 2200 mA DC for a 20% change. It features a tolerance of ±10%, RoHS-compliant termination, and a Sn/Cu 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.
