MH&W International announces the availability of TDK EFD Cores to its line-up of flat pack cores. 15 years ago, TDK developed the EPC core line to serve the need of DC/DC converters requiring low profile transformers. Today we are adding to the EPC line the EFD line of ferrite cores in the most popular sizes of EFD15 – EFD20 – EFD25. The materials that are available are the newer, more advanced materials PC95 and PC47. In addition to the ferrite cores, MH&W also has contracted with a bobbin supplier for a line of bobbins and clips for these EFD cores to provide a complete package.
