Gowanda’s 121AT1002HM is a high-quality horizontal mount standoff toroidal choke designed for reliable performance in electronic applications. With a weight of 12 grams and compact dimensions of 22.86 × 22.86 × 12.7 mm, this component is part of the ATHM series and features surface mount technology (SMT) for easy integration. It offers an inductance of 10 µH with a low direct current resistance (DCR) of 0.01 Ω and a self-resonant frequency (SRF) of 10 MHz. The choke supports a current rating of 8.27 A DC, with incremental current limits of 9000 mA DC for a 10% change and 14000 mA DC for a 20% change. It has a tolerance of ±10% and uses lead (Pb) termination with a Sn63Pb37 finish. Designed to operate in temperatures ranging from -55°C to +130°C, it meets moisture sensitivity level (MSL) 1 standards and is available in bulk packaging.
