The EFD Series

The EFD series (Economic Flat Design) is suitable for applications where an especially flat transformer design is required. The ferrite cores differ from the classic E Series in their flattened, lowered centre limb. The winding structure is thus embedded within the coil former and the ferrite core halves.

All components in the EFD series (EFD10, EFD12, EFD15, EFD20, EFD25 and EFD30) are available from us top-mountable for SMD technology.


  • Material insulation class H 180°C
  • UL listed, combustibility UL 94 V-0
  • 2 x 5 Gullwing connectors for SMD technology
  • Very flat transformer design
  • Application as, for instance, DC/DC converter

Taping of SMD components

On request, we can supply EFD components up to size EFD20 in tape on a delivery reel.

We are also happy to tape other versions if required - please just ask us!
