Problems solved by technology

In addition to the signal line, the high-frequency noise signal brought by the DC power line will also cause electromagnetic interference problems
For the high-frequency noise signal brought by the DC power line, the characteristics of the EMI filter used will also be different. The EMI filter used in the DC power line must withstand a higher current, and under a higher current load, Ordinary magnetic beads have little effect on eliminating electromagnetic interference

Embodiment Construction

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present application clearer, the following combination Figure 1 to Figure 8 And embodiment, this application is described in further detail. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

[0033] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be used for both fixing and circuit communication.

[0034] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right"...

Abstract

The invention discloses a laminated sheet type ferrite bead and a manufacturing method thereof. The method comprises the following steps: respectively manufacturing a ferrite raw ceramic chip and a non-magnetic intermediate interlayer raw ceramic chip from a ferrite material and a non-magnetic intermediate interlayer material; perforating the ferrite raw ceramic chip and the middle interlayer rawceramic chip; arranging an inner electrode coil and upper and lower leading-out parts in the perforated ferrite raw ceramic chip and a perforated middle interlayer raw ceramic chip; filling the ferrite raw ceramic chip and the middle interlayer raw ceramic chip which are provided with the inner electrode coils and the upper and lower leading-out parts with ferrite to obtain a filled ferrite raw ceramic chip and a filled middle interlayer raw ceramic chip; laminating the filled ferrite raw ceramic chip and the filled interlayer raw ceramic chip to obtain a blank block; forming the blank block into a single laminated sheet type component; and manufacturing a terminal electrode for the single laminated chip component. A magnetic bead is manufactured by the method. According to the invention,the magnetic bead has higher current resistance and saturation current.

Description

technical field [0001] The present application relates to the technical field of magnetic beads, in particular to a laminated chip ferrite magnetic bead and a manufacturing method thereof. Background technique [0002] At present, with the acceleration of the operation speed of digital products, the requirements for product response speed are getting higher and higher. In addition to signal lines, high-frequency noise signals brought by DC power lines can also cause electromagnetic interference problems. For the high-frequency noise signal brought by the DC power line, the characteristics of the EMI filter used will also be different. The EMI filter used in the DC power line must withstand higher currents, and under higher current loads, Ordinary magnetic beads do little to eliminate electromagnetic interference. [0003] The disclosure of the above background technical content is only used to assist in understanding the inventive concepts and technical solutions of this a...
