When you are looking at Transformers from Triad Magnetics the “B” suffix is calling out a package quantity from the factory and not a feature on the part.
For example if you are looking at part CST306-1A and comparing to part CST306-1A-B the parts are the same part. On the “B” as you will have a minimum order quantity of 720 units.
The same would be true when looking at Audio Transformer part numbers TY-401P and TY-401P-B. These are the same parts, however the “B” will have a different package quantity, In this case the Minimum order quantity would be 1,200 units.
