Gowanda’s GA20-471KLF 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), making it suitable for COTS+ grade applications. It offers an inductance of 4.7 µH with a direct current resistance (DCR) of 0.022 Ω, supporting a current rating of 3.555 A DC and a saturation current of 7 A DC. The choke has a tolerance of ±10% and is RoHS compliant with a Sn100 termination finish. Constructed with a ferrite core, it operates efficiently across a temperature range of -55°C to +125°C and is rated with a moisture sensitivity level (MSL) of 1, ensuring reliability in various environments. The GA20-471KLF is packaged in tape and reel (T&R) format, although it is not fungal inert and lacks shielding.
