Gowanda’s GA20-331K 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 utilizes through-hole technology (THT) for mounting. It is classified under COTS+ application grade, ensuring reliability in various environments. The choke offers an inductance of 3.3 µH with a direct current resistance (DCR) of 0.016 Ω, supporting a current rating of 4.168 A DC and a saturation current of 7.5 A DC. It maintains a tolerance of ±10% and is constructed with a ferrite core. The termination type is lead-based (Pb) with a Sn63Pb37 finish, and it is not shielded. The GA20-331K operates efficiently within a temperature range of -55°C to +125°C, has a moisture sensitivity level (MSL) of 1, and is available in tape and reel (T&R) packaging. However, it is not fungal inert.
