In order to achieve lower losses in ferrite cores, individual air gaps are usually inserted into the cores. This leads to a delay in core saturation.

However, large air gaps increase the magnetic stray fields and thus cause additional losses in the copper at high frequencies.

Blinzinger Elektronik offers the possibility of inserting distributed air gaps in ferrite cores in order to reduce magnetic stray fields and thus minimize losses in the entire component.

The distributed air gaps can be introduced both in the central leg as well as in the outer legs, which greatly optimizes the emission of the magnetic field into the environment according to the application. Distributed air gaps are available for the core designs E, ETD, ER, PM, PQ, RM as well as U and URR. Mechanically or according to the required AL value.

In addition to these common standard designs, we also offer distributed air gaps in customer-specific core versions.
