Gowanda’s DB4-273 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. This component is part of the DB4 series and utilizes through-hole technology (THT) for mounting. It is classified under the COTS+ application grade, offering an inductance of 270 µH with a direct current resistance (DCR) of 0.05 Ω. The choke supports a current rating of 11.4 A DC and a saturation current of 11.8 A DC, with a tolerance of ±10%. It employs a lead (Pb) termination type with a Sn63Pb37 finish and features a ferrite core. The component is not shielded and operates efficiently within a temperature range of -55°C to +125°C. It is rated with a moisture sensitivity level (MSL) of 1 and is available in bulk packaging. However, it is not fungal inert.
