Mundorf Mundorf Feron i core coils

Mundorf

I-core coils. FERON™, used as a core material, is heat treated after production in a special process. This gives FERON™ a crystal lattice structure that has optimum magnetic properties, offers the lowest loss values and is very resistant to distortion. Their power handling capacities are substantially higher than those of current ferrite core coils while, at the same time, they‘re smaller and less expensive than transformer core coils. Baked varnish coils of this type can be found at the end of this chapter.

Technical specifications:
Tolerance: max. 3%, typical 1.5%
OFC-Copper 99.99% pure 		Coil form: PA, fi bre-glass reinforced
Core material: FERON
Grain-oriented silicon iron 0.35 mm


Please note: The power values Pmax in the following tables were determined at 20 degrees Celsius ambient temperature and free convection. They are just a guideline and - since we are not the manufacturers - cannot be guaranteed by us.
