Gowanda’s GA20-472K 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 high reliability and performance. The choke offers an inductance of 47 µH with a direct current resistance (DCR) of 0.109 Ω, supporting a current rating of 1.597 A DC and a saturation current of 1.8 A DC. It has a tolerance of ±10% and utilizes a ferrite core. The termination type is lead-based (Pb) with a Sn63Pb37 finish, and it is not shielded. The GA20-472K operates effectively within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1, making it suitable for various environments. It is packaged in tape and reel (T&R) format, although it is not fungal inert.
