Gowanda’s GA20-474K 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 suitable for COTS+ grade applications, offering an inductance of 4700 µH with a tolerance of ±10%. The GA20-474K has a direct current resistance (DCR) of 10.5 Ω and supports a current rating of 0.163 A DC, with a saturation current of 0.18 A DC. The termination type is Pb with a Sn63Pb37 finish, and it features a ferrite core. Although it is not shielded, it operates reliably within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. The component is packaged in tape and reel (T&R) format and is not fungal inert.
