Toroidal Tape Cores Production information

Toroidal Tape Cores Production information

€0,00

 

The cores are wound from grain-oriented electrical steel tape in the direction of the grain orientation, resulting in the lowest specific losses with the best permeability, both at low and high inductions.
As standard, we supply all Toroidal Tape Cores with a black protective coating.

 

Art.-Nr.

 

The Toroidal Tape Cores are available in the following versions:

– Tape thickness from  0,10  –  0,30 mm

– normal: For use with protective caps.

– reinforced with synthetic resin: For protection against the mechanical loads exerted by the copper winding.

– coated with epoxy resin: Suitable for direct winding without further protection.

  • temperature-resistant up to 140 °C,
  • Dielectric strength of 40-50 kV/mm
  • Thickness 250 µm.

 

To meet the magnetic requirements, we recommend, as far as possible, the following ratio
