These are the inductors I'm using:
E SERIES HELICAL WINDING OUTPUT INDUCTORS : CWS Coil Winding Specialist, manufacturer of transformers, inductors, coils and chokes
I had actually looked at the Vishay inductors you have, but at the time, all the suppliers I looked at were sold out of them. These guys were the only other supplier I could find that had something similar at a reasonable price.
I do notice that mine get pretty hot when conducting 20A. Of course, they are rated for operation up to 200C, which is insanely hot!
