Gowanda’s GA10-471K 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 GA10 series and utilizes through-hole technology (THT) for mounting. It is classified under the COTS+ application grade, ensuring high reliability and performance. The inductor offers an inductance of 4.7 µH with a direct current resistance (DCR) of 0.022 Ω, supporting a current rating of 3.555 A DC and a saturation current of 3.4 A DC. It operates effectively across a frequency range with a self-resonant frequency (SRF) of 85 MHz and maintains a tolerance of ±10%. The GA10-471K features a lead-based termination type with a Sn63Pb37 finish and is constructed with a ferrite core. It is designed to function in extreme 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 shielded and is not fungal inert.
