Gowanda’s DB3-474LF 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 the COTS+ application grade, offering an inductance of 4700 µH with 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 is RoHS compliant with a Sn63Pb37 termination finish and utilizes a ferrite core. Although not shielded, it operates efficiently within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. The product is available in bulk packaging but is not fungal inert.
