Gowanda’s DB3-821 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) for mounting. It is classified under the COTS+ application grade, offering an inductance of 8.2 µH with a direct current resistance (DCR) of 0.003 Ω. The choke supports a current rating of 21 A DC and a saturation current of 42 A DC, with a tolerance of ±20%. Its construction includes a ferrite core and a leaded termination type with a Sn63Pb37 finish. Although not shielded, it operates effectively within a temperature range of -55°C to +125°C and has a moisture sensitivity level (MSL) of 1. The DB3-821 is packaged in bulk and is not fungal inert.
