Large size ferrite cores for high performance

Large Ferrite cores are used in many fields of power electronics such as solar technology (e. g. transformers for inverters), traction current, charging technology (charging electronics for electric vehicles), inductive heating and many more.

We offer such large-volume ferrite cores for applications with high power requirements. These large size ferrite cores are available in our power material BFM8 and in high permeable materials BFM2k and BFM6k. The BFM8 material offers very low power dissipation and was developed especially for applications with high currents. The frequency range extends up to 500 kHz – best material results are obtained within a working temperature range of -60° to 120° Celsius (- 76° to 248° Fahrenheit) .

Large bobbins are also available for many of our cores – please send your detailed request..

Customer-specified air gaps can be individually inserted in the ferrite cores.
