Gowanda’s DB3-471 is a radial lead high current power line choke designed for demanding applications. Weighing 40 grams and measuring 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 4.7 µH with a direct current resistance (DCR) of 0.003 Ω. The choke supports a current rating of 21 A DC and a saturation current of 54 A DC, with a tolerance of ±20%. It uses a ferrite core and has a termination type of Pb with a Sn63Pb37 finish. Operating efficiently in temperatures ranging from -55°C to +125°C, the DB3-471 is packaged in bulk and has a moisture sensitivity level (MSL) of 1. However, it is not shielded and is not fungal inert.
