Gowanda’s GA40-474KLF 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+ application grades, offering an inductance of 4700 µH with a direct current resistance (DCR) of 3.19 Ω. The choke supports a current rating of 0.378 A DC and a saturation current of 0.395 A DC, with a tolerance of ±10%. It is RoHS compliant with Sn100 termination finish and features a ferrite core. The component operates efficiently within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. It is packaged in tape and reel (T&R) format, although it is not fungal inert.
