Abstract

An inductor device includes a core having a flange attached to one of the end portions, a winding engaged onto the core, and a covering member engaged onto the core and the winding, the covering member includes a number of particles, and includes an outer contour identical to that of the first flange. The covering member includes a quadrilateral shape having four outer surfaces flush with four outer surfaces of the flange. The covering member includes a thickness and dimension (h) equal to that of the flange. The covering member is made of a material selected from a heat curing resin and an ultraviolet curing resin. The particles are selected from ferrite or magnetic powders or particles.

Claims

1. An inductor device comprising:

a core including a first end portion and a second end portion, and including a first flange provided on said first end portion of said core,

a winding engaged onto said core, and

a covering member engaged onto said core and said winding,

wherein said covering member includes a plurality of particles engaged therein, and includes an outer contour identical to that of said first flange.

2. The inductor device as claimed in claim 1, wherein said covering member includes a quadrilateral shape having four outer surfaces flush with four outer surfaces of said first flange.

3. The inductor device as claimed in claim 1, wherein said covering member includes a thickness and dimension (h) equal to that of said first flange.

4. The inductor device as claimed in claim 1, wherein said covering member includes a width and dimension (h) equal to that of said first flange.

5. The inductor device as claimed in claim 1, wherein said covering member is made of a material selected from a heat curing resin and an ultraviolet curing resin.

6. The inductor device as claimed in claim 1, wherein said particles are selected from magnetic particles and magnetic powders.

7. The inductor device as claimed in claim 1, wherein said particles are selected from magnetic attractive particles.

8. The inductor device as claimed in claim 1, wherein said particles are selected from ferrite powders and particles.

9. The inductor device as claimed in claim 1, wherein said core includes a second flange provided on said second end portion of said core.

10. The inductor device as claimed in claim 9, wherein said covering member includes a thickness and dimension (h) greater than that of said second flange of said core.
