Iron Powder Cores

Micrometals are a world renowned manufacturer of Iron Powder Cores and Power Magnetics is proud to represent them as an authorised agent and distributor of their products.

Micrometals Iron Powder Toroidal Cores have a distributed air gap and are available in material grades covering many applications. Typical applications include RF inductors and transformers, lamp dimmer chokes, 60Hz differential-mode EMI chokes and DC output chokes. Micrometals issues two catalogues titled ‘RF Applications’ and ‘Power Conversion & Line Filter Applications’ The contents of each Catalogue is summarised below.

  • Composition >99% Iron
  • Permeabilities up to 100
  • High losses (840 mW/cm3)
  • Operating frequency to >100 KHz
  • BSat (Tesla) 1.5
  • Curie Temperature 770˚C
  • Shape formats: Toroidal; E core; bobbin core; etc.
  • Relative cost – Lowest of all Powder Cores
  • Wide range of different material mixes available to suit many different applications.
  • In general, iron powder cores are lower cost than alloy powder cores
  • Thermal aging needs to be considered when the core is exposed to prolonged elevated temperatures, this causes an irreversible increase in core loss over time. In the overwhelming majority of situations this is not going to be an issue, but if you think it might be, then it is worth considering an alloy powder alternative.
