Problems solved by technology

However, the height of the external lead frame will increase the overall height of the integrated
[0007] Therefore, under the condition that the required inductance value is the same, when the existing inductor is packaged with the IC chip, the overall height cannot be reduced, which is not conducive to thinner design

Abstract

The invention discloses an inductor, which comprises a first core, a wire, a second core and first wire holders. The first side of the first core is provided with a holding space, moreover, the second side of the first core is provided with concave parts, wherein the first side is opposite to the second side. The first core has a first height. The wire is arranged in the holding space. The second core is arranged on the first side of the first core, and covers the holding space. The first wire holders are provided with embedding parts, which are embedded in the concave parts. Each embedding part has a second height. After the embedding parts are embedded in the concave parts of the first core, the total height of the embedding parts and the first core is less than the sum of the first height and the second height. The invention embeds the wire holders of the inductor in the core. When the inductor and an IC (Integrated Circuit) chip are in system-in-package , the overall height can be effectively reduced, and thereby an electronic product can be easily designed to be thin.

Description

[0001] This application is a divisional application of the Chinese invention patent application with the application number 201110020446.7, the application date is January 7, 2011, and the invention name is "inductor". technical field [0002] The invention relates to an inductor, in particular to an inductor capable of system integration package (System-In-Package, SIP) with an IC chip. Background technique [0003] An inductor is a passive electronic component that stores energy generated by a current passing through a magnetic field. The inductance value is used to measure the ability of an inductor to store magnetic energy. Inductors are generally wound in the shape of a coil with wire, and according to Faraday's Law of Induction, the number of turns of wire wound can enhance the magnetic field in the coil. Inductance is created by the magnetic field formed around a current-carrying conductor, which has a tendency to resist changes in current. The number of turns of the...
