Gowanda’s DB3-474 is a high-quality radial lead high current power line choke designed for demanding applications. With a weight of 40 grams and dimensions of 20.96 × 27.94 × 27.94 mm, this component is part of the DB3 series and features through-hole technology (THT) mounting. It is suitable for COTS+ grade applications, offering an inductance of 4700 µH and a direct current resistance (DCR) of 1.7 Ω. The choke supports a current rating of 1 A DC and a saturation current of 1.7 A DC, with a tolerance of ±10%. It utilizes a ferrite core and has a termination type of Pb with a Sn63Pb37 finish. Operating effectively in temperatures ranging from -55°C to +125°C, it is packaged in bulk and has a moisture sensitivity level (MSL) of 1. However, it is not shielded and is not fungal inert.
