Gowanda’s GA30-272K 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 2 grams. This component is part of the GA30 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 27 µH with a direct current resistance (DCR) of 0.028 Ω, supporting a current rating of 4.031 A DC and a saturation current of 2 A DC. It operates effectively within a frequency range up to 8.5 MHz and maintains a tolerance of ±10%. The termination type is lead-based (Pb) with a Sn63Pb37 finish, and it utilizes a ferrite core. Although it is not shielded, the GA30-272K is capable of operating in temperatures ranging from -55°C to +125°C, with a moisture sensitivity level (MSL) of 1, and is packaged in tape and reel (T&R) format. However, it is not fungal inert.
