Gowanda’s 121AT1002HC is a high-quality Horizontal Encapsulated Toroidal Power Choke, part of the ATHC series, designed for surface mount technology (SMT) applications. It features an inductance of 10 µH with a direct current resistance (DCR) of 0.01 Ω and a self-resonant frequency (SRF) of 10 MHz. The component supports a current rating of 8.27 A DC and can handle incremental current changes of 9000 mA DC at a 10% inductance drop and 14000 mA DC at a 20% drop. With a tolerance of ±10%, it is built with a Pb termination type and a Sn63Pb37 termination finish. The choke operates efficiently across a wide temperature range from -55°C to +130°C and is classified with a moisture sensitivity level (MSL) of 1, ensuring reliability in various environments. It is available in bulk packaging, weighing 16 grams, and measures 24.13 × 24.13 × 13.97 mm.
