Gowanda’s GA40-272K 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 tailored for through-hole technology (THT) mounting and meets COTS+ application grade standards. It offers an inductance of 27 µH with a direct current resistance (DCR) of 0.027 Ω, supporting a current rating of 4.105 A DC and a saturation current of 5.36 A DC, with a tolerance of ±10%. The termination type is lead-based with a Sn63Pb37 finish, and it utilizes a ferrite core. Although not shielded, it operates efficiently within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. Packaged in tape and reel (T&R) format, it is not fungal inert, making it a reliable choice for various electronic applications.
