Problems solved by technology

[0009] The skin effect (Skin Effect) and parasitic effect (Parasitic Effect) caused by the increase of AC frequency lead to the increase of AC resistance and the increase of equivalent series resistance
[0010] That is, as the interlayer distance of the coil and the distance between the coil and the external electrode become smaller, the equivalent series resistance becomes larger due to the proximity effect and the rise of parasitic capacitance, and becomes larger as the frequency becomes higher due to the skin effect large, resulting in reduced Q characteristics

Abstract

The invention discloses a stack-up electronic part and a manufacturing method thereof. The stack-up electronic part comprises a stack-up part, which is provided with a plurality of insulation layers and internal coil parts disposed on the insulation layers in a stack-up manner; an external electrode, which is disposed on the outer side of the stack-up body, and is connected with the internal coil parts. The internal coil parts are used to form step difference on a cross section in the width-thickness direction of the stack-up body.

Description

technical field [0001] The present invention relates to a laminated electronic component and its manufacturing method. Background technique [0002] Inductors, one of electronic components, are representative passive components that form circuits together with resistors and capacitors to eliminate noise, and are used in resonant circuits, filter circuits, etc., using electromagnetic characteristics and capacitors. Combining to increase the signal of a specific frequency band. [0003] In a laminated inductor, a coil pattern is formed on an insulator sheet mainly made of a magnetic material using a conductive paste or the like and laminated to form a coil inside a laminated sintered body to realize inductance. [0004] There is known a vertically laminated inductor in which an internal coil is formed in a vertical direction with respect to a substrate mounting surface in order to achieve higher inductance. Compared with a stacked inductor whose internal coils are formed alo...
