Gowanda’s GA30-474K is a high current power choke designed for demanding applications, featuring a robust construction with a weight of 2 grams and dimensions of 22.86 × 11.43 × 11.43 mm. Part of the GA30 series, this component is tailored for COTS+ application grade, ensuring reliability and performance. It offers an inductance of 4700 µH with a DCR of 3.79 Ω, and supports a current rating of 0.346 A DC, with a saturation current of 0.15 A DC. The choke operates effectively within a frequency range up to 0.32 MHz and maintains a tolerance of ±10%. It is designed for through-hole mounting (THT) and features a Pb termination type with a Sn63Pb37 finish. The core is made of ferrite, and it is not shielded. It operates across a wide temperature range 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.
