Gowanda’s 121AT7502VC is a high-quality vertical mount encapsulated toroidal choke designed for reliable performance in demanding applications. With a weight of 12 grams and compact dimensions of 20.32 × 12.7 × 24.13 mm, this component is part of the ATVC series and features through-hole technology (THT) for secure mounting. It is suitable for COTS+ application grades, offering an inductance of 75 µH and a low DC resistance of 0.045 Ω. The choke has a self-resonant frequency of 2.5 MHz and a current rating of 3.9 A DC, with incremental current limits of 3900 mA DC for a 10% inductance change and 5800 mA DC for a 20% change. It boasts a tolerance of ±10% and uses leaded (Pb) terminations with a Sn63Pb37 finish. The component operates efficiently across a wide temperature range from -55°C to +130°C, has a moisture sensitivity level (MSL) of 1, and is available in bulk packaging.
