Gowanda’s GA40-683K is a high current power choke designed for demanding applications, featuring a compact size with dimensions of 22.86 × 11.43 × 11.43 mm and a weight of 7 grams. This component is part of the GA40 series and is mounted using through-hole technology (THT). It is suitable for COTS+ grade applications, offering an inductance of 680 µH with a tolerance of ±10%. The GA40-683K has a direct current resistance (DCR) of 0.548 Ω and can handle a current rating of 0.911 A DC, with a saturation current of 1.05 A DC. The choke is constructed with a ferrite core and features a lead (Pb) termination type with a Sn63Pb37 finish. It operates effectively within a temperature range of -55°C to +125°C and is rated with a moisture sensitivity level (MSL) of 1. The component is packaged in tape and reel (T&R) format, although it is not fungal inert and lacks shielding.
