To make coupled inductor selection easy, Eaton Coiltronics has selection guides that will help a designer quickly find inductance, current ratings and DC resistance. Below the images in this guide are the footprint dimensions and height of each part. On the left hand side, select the desired inductance. Reading the guide across from left to right, the current rating in amps (bold text) and the DC resistance (DCR) for the inductor is shown. Move to the right until the current rating meets or exceeds the need and this will be the smallest dual winding inductor that will work in the application based upon the inductance value selected on the left. The guide shown on this slide features the ferrite core shielded drum dual inductor families. Inductor images contain links to the online data sheets.
