At least one shielding layer made of conductive material is formed on a body of a magnetic device to prevent magnetic fields from leaking to the outside of the magnetic device so as to reduce EMI and the size of the magnetic device.

Shielded magnetic device and the method to make the same

Mixed magnetic powders for making a magnetic core or body is disclosed, wherein the mixed magnetic powders comprises a first magnetic powder and a second magnetic powder, each of the first magnetic powder and the second magnetic powder being made of a soft magnetic material, wherein the average particle diameter of the first magnetic powder is greater than that of the second magnetic powder, and each of the first magnetic powder and the second magnetic powder has a pre-configured particle size distribution for increasing the density of the magnetic body.

Mixed magnetic powders and the electronic device using the same

Mixed magnetic powders for making a magnetic core or body is disclosed, wherein the mixed magnetic powders comprises: a first magnetic powder; a second magnetic powder, wherein the first magnetic powder and the second magnetic powder are made of a same soft magnetic material, wherein the ratio of the D50 of the first magnetic powder to the D50 of the second magnetic powder is in the range of 5 to 12, wherein the first magnetic powder weighs 50 to 90 percent of the total weight of the first magnetic powder and the second magnetic powder; and the second magnetic powder weighs 10 to 50 percent of the total weight of the first magnetic powder and the second magnetic powder.
