Embodiment Construction
[0042] The present invention will be further described in detail below through embodiments in conjunction with the accompanying drawings.
[0043] Such as Figure 1A1 , 1A2 As shown, the NiZn ferrite I-shaped magnetic core can be made by injection molding process, the magnetic permeability is preferably 3000~5000, and the saturation magnetic flux is 400~500mT. Preferably, there are two parallel electrode slots 101, 102 at the bottom of the magnetic core. The metallization layers 103 and 104 are preferably formed inside the electrode groove by a sputtering process.
[0044] A winding machine can be used to wind the wire on the above-mentioned I-shaped magnetic core center column 105 . Such as Figure 1B As shown, preferably, the coil lead-out ends 106, 107 are received into the electrode slots 101, 102 after the coil winding product is completed.
[0045] Figure 1C It is a schematic diagram of the finished product formed after wrapping the winding with a magnetic plastic ...
