Gowanda’s DB4-274 is a high-quality 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) for mounting. It is suitable for COTS+ grade applications, offering an inductance of 2700 µH, a direct current resistance (DCR) of 0.5 Ω, and a current rating of 4 A DC with a saturation current of 3.8 A DC. The choke has a tolerance of ±10% and uses a lead-based termination type with a Sn63Pb37 finish. Its ferrite core is not shielded, and it operates effectively within a temperature range of -55°C to +125°C. The component is rated with a moisture sensitivity level (MSL) of 1 and is packaged in bulk, though it is not fungal inert.
