Gowanda’s 050AT3901HM is a high-quality horizontal mount standoff toroidal choke, part of the ATHM series, designed for surface mount technology (SMT) applications. It features an inductance of 3.9 µH with a direct current resistance (DCR) of 0.006 Ω and a self-resonant frequency (SRF) of 35 MHz. The component supports a current rating of 9.5 A DC, with incremental current levels of 8500 mA DC for a 10% inductance change and 12000 mA DC for a 20% change. It has a tolerance of ±15% and utilizes a Pb termination type with a Sn63Pb37 finish. The choke operates efficiently within a temperature range of -55°C to +130°C and is rated at moisture sensitivity level (MSL) 1, ensuring reliability in various environments. The product is packaged in bulk, weighing 7 grams, with dimensions of 16.76 × 16.76 × 10.67 mm.
