Gowanda’s GA10-391K 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. Part of the GA10 series, this component is tailored for COTS+ application grade, ensuring reliability and performance. It offers an inductance of 3.9 µH with a DCR of 0.017 Ω, supporting a current rating of 4.044 A DC and a saturation current of 3.6 A DC. The choke operates efficiently across a frequency range with an SRF of 90 MHz and maintains a tolerance of ±10%. Constructed with a ferrite core and a Pb termination type with a Sn63Pb37 finish, it is suitable for through-hole technology (THT) mounting. The GA10-391K is designed to function in extreme temperatures from -55°C to +125°C, with a moisture sensitivity level of 1, and is packaged in tape and reel (T&R) format.
