Gowanda’s DB3-472 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 classified under COTS+ application grade, offering an inductance of 47 µH with a direct current resistance (DCR) of 0.018 Ω. The choke supports a current rating of 9 A DC and a saturation current of 19 A DC, with a tolerance of ±10%. It uses a ferrite core and has a lead-based termination type with a Sn63Pb37 finish. Operating efficiently 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.
