Gowanda’s DB4-394 is a radial lead high current power line choke designed for demanding applications. With a weight of 118 grams and dimensions of 27.94 × 38.1 × 38.1 mm, this component is part of the DB4 series and features through-hole technology (THT) mounting. It is suitable for COTS+ grade applications, offering an inductance of 3900 µH, a direct current resistance (DCR) of 0.7 Ω, and a current rating of 2.8 A DC, with a saturation current of 3.1 A DC. The component has a tolerance of ±10% and utilizes a lead (Pb) termination type with a Sn63Pb37 finish. Constructed with a ferrite core, it operates effectively within a temperature range of -55°C to +125°C and is rated with a moisture sensitivity level (MSL) of 1. The DB4-394 is packaged in bulk and is not shielded or fungal inert.
