    I have about 300 files in my computer concerning   
    coupled inductors, they're all the rage these days.   
    Most providers, and there are many, use the term   
    coupled inductor.  Your DRQ supplier, SRF and a   
    few others call them "dual winding."  TI and other   
    app note writers call them coupled inductors.  Both   
    Coilcraft and Coilmaster, who have piles of offerings,   
    call them coupled inductors.  Ditto Vishay and Wurth.   
    Published peer-reviewed papers say coupled inductors.   
      
    If you want to search for them, coupled inductors is   
    the phrase.  Octopart comes up with about 1500 parts   
    that way, but only 184 searching for dual winding.   
    Of course, they're all the same bifilar wound stuff,   
    but that search term gets zero hits at Octopart. And   
    the O.P's title, bifilar inductor, gets only 5 hits.
