Toroidal Cores

Telcon high permeability strip wound cores are manufactured to the highest international standards, in a range of alloys and sizes developed to meet the most stringent specifications, and are used in a variety of applications. Core manufacturing, including winding and heat treatment, is carried out and controlled using processes and machines specially developed by Telcon.

There are a variety of finishes to the cores from Epoxy Resin Coated, Impregnated, Loctite, Plain or Cased.

 

Telcon Torodial Cores

 

Soft Ferrite Cores

Soft ferrite is the most popular and cost effective material used in high frequency applications.

In high frequency power conversion system ferrite materials have saturation flux in the range of 0,3¸0,5 Tesla and some thousands of relative permeability. Therefore, ferrite materials have quite low saturation flux, that is the most critical limit for inductive components, especially in case of high DC currents or high overcurrent risk. Ferrite materials for power application have the great advantage of low losses level on a wide frequency range.

 

Amorphous and Nanocrystalline Laminated Cores

Amorphous and nanocrystalline laminations are obtained by a special rapid quenching technology. Typical thicknesses of those laminations are few tens of μm. Amorphous cores are suitable for output inductors, when high DC current, low ripple current, extremely compact dimensions. High saturation flux level is suitable for high currents and low ripple current doesn't cause critical core losses.

Nanocrystalline cores have vary low losses, even for high variation of magnetic flux, so they can be used for switching transformers too.

Sirio Inductors

 

Powder Cores

Powder cores differ in chemical composition. Powder cores are pressed with an organic or inorganic binder, that is responsible for storage of energy. Each material, identified by the producer with a code or a commercial name, possesses its own characteristics in terms of permeability, saturation flux, specific losses. They are typically very stable with the temperature and they can be used in critical environment applications. Powder cores are more expensive than ferrite cores, but normally cheaper than amorphous and nanocrystalline ones.
