[---Image_alt---] Ferrites Air Gaps PB

Content

Single air gaps are a common technique to delay the core saturation and to increase the power handling capability. However, a single large air gap leads to a high fringing flux effect.

  • EPCOS offers a core manufacturing technique of distributed air gaps that significantly reduces the fringing flux effect in order to reduce electromagnetic emissions and heating.
  • This technical solution is available or may be manufactured for E, EQ, ER, ETD, PM and PQ cores
  • Distributed air gaps are used in the design of power chokes and flyback converters.
  • EPCOS is the first manufacturer of ferrite cores with distributed air gaps to provide the marketplace with an economical solution focussing on higher efficiency and downsizing.
