Pulverkerne – eine Einführung

Logo Micrometals Arnold Powder Cores

Powder cores are made ​​of tiny particles of ferromagnetic powder. Before the actual cores are produced, each powder particle is coated with a thin layer of electrically insulating material. The powder is then compressed under high pressure into the core die. The electrical insulation of the particles against each other thus enables the use of the cores at high frequencies. In addition, this isolation provides a 'distributed air gap' 'over the entire core. This leads to a high DC-bias and a smooth saturation.
