Gowanda’s DB3-561 is a radial lead high current power line choke designed for demanding applications, featuring a compact size with dimensions of 20.96 × 27.94 × 27.94 mm and a weight of 40 g. This component is part of the DB3 series and is suitable for COTS+ grade applications. It offers an inductance of 5.6 µH, a low DCR of 0.003 Ω, and a high current rating of 21 A DC, with a saturation current of 54 A DC. The choke has a tolerance of ±20% and utilizes a ferrite core. It is not shielded and operates effectively within a temperature range of -55°C to +125°C. The termination type is Pb with a Sn63Pb37 finish, and it is mounted using THT. The DB3-561 is packaged in bulk and has an MSL of 1, although it is not fungal inert.
