Gowanda’s 050KM3303HM is a high-efficiency horizontal mount standoff toroidal choke, designed for superior performance in demanding applications. Weighing 7 grams and measuring 16.76 × 16.76 × 10.67 mm, this component is part of the KMHM series and features surface mount technology (SMT) for ease of integration. It is classified as COTS+ grade, ensuring reliability in commercial off-the-shelf applications. With an inductance of 330 µH, a direct current resistance (DCR) of 0.19 Ω, and a self-resonant frequency (SRF) of 1 MHz, it supports a current rating of 1.69 A DC. The component can handle incremental current levels with a 10% inductance change at 270 mA DC and a 20% change at 500 mA DC, maintaining a tolerance of ±10%. Its termination type is lead-based with a Sn63Pb37 finish, and it operates efficiently across a temperature range of -55°C to +130°C. The component is rated at moisture sensitivity level (MSL) 1 and is available in bulk packaging.
