Project Description

ferrite pm coresFerrite PM Cores

Ferrite PM cores are a variation on classic P cores, suitable for large high power transformers and energy storage chokes. They have larger wire slots facilitating easy assembly, but still the good shielding of a closed core shape. PM cores can be found in transmission and radar equipment and in various high power industrial installations.

Summary:

  • Good shielding
  • Easy assembly
  • Robust core shape
  • Available in state of the art power materials
