Magnetic particle core
2 year ago
Toroidal Core
Soft magnetic powder core is a kind of soft magnetic composite based on alloy powder with micron size. It is produced by high resistivity insulation coating, high-pressure compaction, annealing and other processes. As a new generation of soft magnetic material after sili- con steel, ferrite, amorphous alloy and nanocrystalline alloy, it has the advantages of both metallic magnetic material and oxide magnetic material and has been acknowledged as the most suitable core for power electronics device developing towards high frequency, high power, energy saving and small size.
Advantages of Soft Magnetic Powder Core:
1. High saturation flux density
2.Good DC-bias performance
3.High resistivity and low eddy-current loss
4. Good thermal and frequency stability of magnetic properties
