Gowanda’s 121KM5002HMLF is a high-efficiency horizontal mount standoff toroidal choke designed for demanding applications. Part of the KMHM series, this component features a compact design with dimensions of 22.86 × 22.86 × 12.7 mm and a weight of 12 grams, making it suitable for space-constrained environments. It offers an inductance of 50 µH with a tolerance of ±10%, and a low DCR of 0.03 Ω, ensuring minimal energy loss. The choke supports a current rating of 4.77 A DC and can handle incremental current levels of 2300 mA DC (Δ10%) and 4000 mA DC (Δ20%). With a self-resonant frequency of 2.5 MHz, it is ideal for high-frequency applications. The component is RoHS compliant with Sn/Cu termination finish and is designed for surface mount technology (SMT) applications. It operates reliably across a wide temperature range from -55°C to +130°C and is packaged in bulk, meeting the COTS+ application grade standards.
