Abstract
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.
Claims20
A magnetic device, comprising:
- a body;
- and
- at least one conductive layer, wherein the at least one conductive layer is formed on the body, wherein the at least one conductive layer covers at least the top surface of the body for shielding the magnetic device.
A magnetic device, comprising a body and a coil disposed in the body, wherein the body has a top surface, a bottom surface and a first lateral surface connecting the top surface and the bottom surface;
- and a conductive casing, disposed on the body for shielding the magnetic device, wherein the conductive casing covers the top surface of the body and extends to a plurality of lateral surfaces of the body, wherein there is no gap between any two portions of the conductive casing.
