Gowanda’s GA40-392K is a high current power choke designed for demanding applications, featuring a weight of 7 grams and compact dimensions of 22.86 × 11.43 × 11.43 mm. Part of the GA40 series, this component is mounted using through-hole technology (THT) and is classified under the COTS+ application grade. It offers an inductance of 39 µH with a direct current resistance (DCR) of 0.033 Ω, supporting a current rating of 3.713 A DC and a saturation current of 4.36 A DC, with a tolerance of ±10%. The choke uses a ferrite core and is not shielded, operating efficiently within a temperature range of -55°C to +125°C. It features a Pb termination type with a Sn63Pb37 finish, ensuring reliable performance. The component is rated with a moisture sensitivity level (MSL) of 1 and is packaged in tape and reel (T&R) format, although it is not fungal inert.
