Gowanda’s DB4-474 is a radial lead high current power line choke designed for demanding applications, featuring a weight of 118 grams and dimensions of 27.94 × 38.1 × 38.1 mm. Part of the DB4 series, this component is mounted using through-hole technology (THT) and is classified as COTS+ application grade. It offers an inductance of 4700 µH with a direct current resistance (DCR) of 0.757 ohms and supports a current rating of 2 A DC, with a saturation current of 2.9 A DC. The choke has a tolerance of ±10% and utilizes a lead (Pb) termination type with a Sn63Pb37 finish. Constructed with a ferrite core, it 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.
