I am pretty new to KiCAD and although I really like it I am struggeling trying to find the housings and possibly their 3D-Part. As an example: I am looking for IR transistor IRFR7440PbF which has D-Pak housing. Which strategy should I use where can I find it or find out that it does not exists yet?
I also encountered trouble to download footprints from “http://library.oshec.org/” by downloading .mod files. They did not open in KiCAD.
