Problems solved by technology
Also because of its complex production and high cost, this type of power inductor has certain defects.
[0007] From the above-mentioned Murata antenna, since it is all made of oil-sintered magnetic powder and pressed together, its strength will be greatly affected. During the actual processing and use, the antenna will break, such as figure 2 shown

Embodiment Construction
[0044] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0045] Such as image 3 , Figure 4 As shown, a new type of power inductor described in the present invention adopts a laminated structure, the outermost layer is a cover film 1, and under the cover film are a wire layer 2, a PP resin layer 3 and a BT resin layer 4 in sequence, and the innermost layer There is a groove in the middle of the BT resin layer, and a ferrite 5 with the same size as the groove is embedded in the groove, and the wire is wrapped around the outside of the PP resin layer 3 and the BT resin layer 4 wrapped with ferrite.
[0046] The cover film, the PP resin layer and the BT resin layer are combined by pressing. The thicknesses of the cover film, PP resin layer and BT resin layer are respectively 40um-60um, 10um-30um, 300-350um. In this embodiment, the length, width and thickness of the power inductor are 10mm*5mm*0.47mm...

Abstract
The invention relates to a novel power inductor and a manufacturing method of the novel power inductor. The novel power inductor comprises a ferrite (5) and a wire arranged on the periphery of the ferrite (5) in a wound mode. The novel power inductor is of a laminated structure, a covering film (1) is arranged in the outermost layer, a wire layer (2), a PP resin layer (3) and a BT resin layer (4) are sequentially arranged below the covering film (1), a groove is formed in the middle of the BT resin layer (4) in the innermost layer, the ferrite (5) same as the groove in size is buried in the groove, and the PP resin layer (3) and the BT resin layer (4) provided with the ferrite (5) in a wrapping mode are surrounded with the wire. The novel power inductor is flexible in product form, low in manufacturing cost, free of cracks in machining and practical use, and free of the condition that the radio-frequency performance is invalid even when the novel power inductor bears pressure.
Description
technical field [0001] The invention belongs to the technical field of smart card production, and in particular relates to a novel power inductor and a production method thereof. Background technique [0002] Power inductors, also known as chip inductors and high-current inductors, are electromagnetic induction elements wound with insulated wires. They are commonly used inductive elements. Their advantages are: [0003] 1. Surface mount high power inductors; [0004] 2. It has the characteristics of miniaturization, high quality, high energy storage and low resistance; [0005] 3. Reel packaging can be provided, which is suitable for surface automatic mounting, etc. [0006] With more and more smart card products for mobile payment, such as figure 1 As shown, a power inductor (Murata antenna) has been invented by Murata. The inductor is integrated on the smart card to enhance the radio frequency effect. In actual use and processing, there is a risk of fracture. Once thi...
