CSC Magnet Core

What is the CSC magnet core?

CSC magnet core are distributed air gap cores made from ferrous alloy powders for losses at elevated frequencies. Small air gaps distributed evenly throughout the cores increase the amount of DC that can be passed through the winding before core saturation occurs. Powder cores are excellent as low loss inductors for SMPS, switching regulators, Noise filters, etc.
