Gowanda’s GA20-391K is a high current power choke designed for demanding applications, featuring a compact size with dimensions of 16 × 6.6 × 6.6 mm and a weight of 2 grams. This component is part of the GA20 series and is mounted using through-hole technology (THT). It is classified under the COTS+ application grade, ensuring reliability in commercial off-the-shelf applications. The choke offers an inductance of 3.9 µH with a direct current resistance (DCR) of 0.017 Ω, supporting a current rating of 4.044 A DC and a saturation current of 7.4 A DC, with a tolerance of ±10%. The termination type is lead-based (Pb) with a Sn63Pb37 finish, and it utilizes a ferrite core. Although it is not shielded, it operates efficiently within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. The product is available in tape and reel (T&R) packaging, though it is not fungal inert.
