Gowanda’s DB4-473 is a radial lead high current power line choke designed for demanding applications. Weighing 118 grams and measuring 27.94 × 38.1 × 38.1 mm, this component is part of the DB4 series and features through-hole technology (THT) mounting. It is classified under COTS+ application grade, offering an inductance of 470 µH with a direct current resistance (DCR) of 0.076 Ω. The choke supports a current rating of 7.2 A DC and a saturation current of 9.2 A DC, with a tolerance of ±10%. Its termination type is Pb with a Sn63Pb37 finish, and it utilizes a ferrite core. The component is not shielded and operates within a temperature range of -55°C to +125°C. It has a moisture sensitivity level (MSL) of 1 and is packaged in bulk, though it is not fungal inert.
