Gowanda’s DB3-472LF 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 is RoHS compliant with Sn100 termination finish and utilizes a ferrite core. Operating efficiently within a temperature range of -55°C to +125°C, the DB3-472LF is packaged in bulk and has a moisture sensitivity level (MSL) of 1. However, it is not fungal inert and is not shielded.
