Multilayer electronic element and communication device

Abstract

A multilayer electronic component has a multilayered product laminating a plurality of dielectric sheets as one piece, a plurality of grounded electrodes provided among the dielectric sheets being different inside the multilayered product, and inductor electrodes provided on the dielectric sheet surfaces not having the plurality of grounded electrodes inside the multilayered product, wherein all or part of the inductor electrodes are placed so as not to be sandwiched by the plurality of grounded electrodes.

Description

technical field [0001] The present invention relates to multilayer electronic components used in mobile communication devices, such as mobile phones and the like. Background technique [0002] In recent years, as communication devices have become smaller, multilayer electronic components have been frequently used in circuits of mobile phones and the like. Multilayer electronic components include inductors, capacitors, etc. in electrical equipment, filters, switching circuits, etc., and SAW and semiconductors are mounted on top of them, so it can be further miniaturized by integrating composite devices. [0003] The above-mentioned existing multilayer electronic components will be discussed below with reference to the accompanying drawings. [0004] Figure 13 is an internal view of an existing electronic component. The multilayer electronic component has dielectric layers 1301 to 1304 respectively laminated. Dielectric layer 1302 has ground electrode 1305 disposed thereon...

AI Technical Summary

Problems solved by technology

[0005] However, the above configuration has the problem that the impedance becomes low due to the proximity of the inductor electrodes 1306 and 1307 to the ground electrodes 1305 and 1308, so in the case where high impedance is required, an external inductor 1309 needs to be connected separately

[0006] In addition, there is a problem that good insulation between the inductor electrodes cannot be maintained because the inductor electrodes 1306 and 1307 are in close proximity and electromagnetic field coupling is formed.
