Ferrotron 559H

Ferrotron 559HFerrotron 559H

(Frequency: Up to 3000 kHz)

Proven flux concentrator performance with the highest dielectric strength in the Fluxtrol family of machinable soft magnetic materials and lowest losses at high frequencies. Almost constant magnetic permeability over a range of magnetic flux densities and frequencies. Material has good mechanical strength and thermal conductivity. Regarded by many to have the best machinability of the Fluxtrol family of materials.

Note: There are many variables involved in an induction process. In order to utilize the fullest potential of our product, you must help narrow down the parameters you are operating with. Each grade of Fluxtrol material has its own distinctive properties that are beneficial to a certain range of electrical and design parameters.
