Embodiment 1
[0128] Multilayer ceramic capacitors and interposers having the dimensions shown in Table 1 were prepared, and the multilayer ceramic capacitors were mounted on one main surface side of the substrate main body of the interposer to manufacture electronic components. In Example 1, the width W of the effective area of the laminate 11e than the width of the substrate body W 21 Still big. In addition, when the width of the laminated body is set to W 11 , set the thickness of the laminated body as T 11 , Set the thickness of the substrate body as T 21 when W 11 / (T 11 +T 21 ) has a value of 1.05.

Abstract
The invention provides an electronic component which improves noise impression and capacitance of superposed capacitors while excellent balance is realized. The electronic component includes a multilayer capacitor and an interposer including a substrate main body with an electric insulation property, the multilayer capacitor being mounted on one main surface side of the substrate main body. The multilayer capacitor includes a multilayer body, a first outer electrode, and a second outer electrode. The multilayer body includes an effective region and a non-effective region surrounding the effective region. A width of the effective region is larger than a width of the substrate main body, when a width of the multilayer body is represented by W11, a thickness of the multilayer body is represented by T11, and a thickness of the substrate main body is represented by T21, a value of W11 / (T11+T21) is not less than about 0.90 and not more than about 1.10.
Description
technical field [0001] The present invention relates to an electronic component including a multilayer capacitor and an interposer. Background technique [0002] In recent years, along with the improvement in performance of electronic equipment, the increase in the capacitance of multilayer ceramic capacitors has progressed. In multilayer ceramic capacitors with large capacitance, ceramic materials with a high dielectric constant such as barium titanate are used as the dielectric material. [0003] These high-permittivity ceramic materials have piezoelectricity and electrostriction, so in a multilayer ceramic capacitor including a dielectric composed of a high-permittivity ceramic material, mechanical strain occurs when a voltage is applied . [0004] Therefore, when an AC voltage or a DC voltage superimposed with an AC component is applied to the multilayer ceramic capacitor mounted on the circuit board, the multilayer ceramic capacitor vibrates due to the strain of the m...
