Technical Information:
Ferrite filters provide an easy and efficient way of reducing both radiated and conducted
interference. KYCON uses a medium permeability nickel zinc ferrite material that is most
effective at attenuating frequencies above 30MHz.

The above chart is typical performance data for a 2.8mm thick ferrite plate at room
temperature. Impedance will be reduced by increased temperature (down approx. 15%
at 100°C at 25MHz) and by increased DC bias (down approx. 15% at 1 amp at 25MHz).
Also, impedance varies with ferrite thickness. Please contact our technical support for
data specific to your application.
