Kaschke ferrite news - Improved medium permeability material K7000

Kaschke ferrite news - Improved medium permeability material K7000

Inductive components with ferrite cores generally exhibit excellent properties in the high frequency range. For EMI or wideband applications, medium and high permeability NiZn (Nickel-Zinc) or MnZn (Manganese-Zinc) ferrites are the preferred choice.

For applications like common-mode chokes, Kaschke has improved the existing K6000 material.

 

The new K7000 ferrite shows higher initial permeability, impedance and insertion losses, while flux density and Curie temperature remain unchanged.

The new K7000 ferrite is available for ring cores in the range from 20mm outer diameter up to 63mm (other sizes on request). The cores can be supplied coated or uncoated. The coating is a  two component epoxy lacquer which gives a good electrical insulation between the winding and the core. Depending on the core size, the breakdown voltage is ≥2kV.

Samples can be requested at Heynen.
