3 1. Toroidal Core 2. What is Powder Core? Powder Cores are distributed air gap cores made from ferrous alloy powders for low 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. 3. Manufacturing process Powder Making Ceramic Insulation Pressing Core Annealing Core Finish Inspection Material Composition High Flux : CH Ni + Fe Alloy Sendust : CS Mega Flux : CK MPP : CM Fe + Si +Al Alloy Fe + Si Alloy Ni + Fe + Mo Alloy
