Ring Cores (MPP, High Flux, KooL Mu, XFlux)

LEPCOS is an authorized distributor of Magnetics in Russia, CIS and Baltic countries.

Magnetics Inc. issues 33 standard sizes of powder ring cores with a distributed gap made of MPP, High Flux, Kool Mμ MAX, Kool Mμ, 75-Series, XFlux materials characterized by high saturation magnetic flux density, with an outer diameter from 3.56 mm to 165.1 mm (including coating).

Ring Cores (MPP, High Flux, KooL Mμ, XFlux)

Ring powder cores are used typically as magnetic circuits of output DC chokes in pulse power supplies, of flyback transformers and of differential chokes.. MPP cores are widely used as magnetic circuits of high-precision inductance coils being stable in wide range of temperature. Absence of organic filing materials within Magnetics’s powder cores and also a high Curie temperature provide an absence of thermal ageing and preservation of stable parameters of products based on these cores on constant operation at high temperatures.

Powder ring cores produced by Magnetics Inc. are also characterized by a strict requirements for inductance coefficient tolerance (from 2% to 8%).

Among advantages one can note:

  • Possibility to select an optimal variant among different powder materials . A Wide range of standard size types
  • High-quality protective dielectric coating (epoxy or parylene), which facilitates the winding process and improves the protection properties of the core's material from adverse environmental influence
  • Low cost
