Description

  The present invention relates to a multilayer capacitor and a method for adjusting an equivalent series resistance of the multilayer capacitor.

  As this type of multilayer capacitor, one having a multilayer body in which a plurality of dielectric layers and a plurality of internal electrodes are alternately stacked and a plurality of terminal electrodes formed in the multilayer body is known ( For example, see Patent Document 1).

  In a power supply for supplying power to a central processing unit (CPU) mounted on a digital electronic device, the load current is increasing while the voltage is lowered. Therefore, it has become very difficult to keep the fluctuation of the power supply voltage within an allowable value against a sudden change in the load current, so that a multilayer capacitor called a decoupling capacitor is connected to the power supply. A current is supplied from the multilayer capacitor to the CPU when the load current changes transiently to suppress fluctuations in the power supply voltage.

In recent years, as the operating frequency of CPUs has further increased, the load current has become higher at higher speeds. For multilayer capacitors used as decoupling capacitors, the equivalent series resistance (ESR) has been increased along with the increase in capacity. There is a demand to increase the size. In the multilayer capacitor described in Patent Document 1, the terminal electrode has a multilayer structure including an internal resistance layer, thereby increasing the ESR.

  However, the multilayer capacitor described in Patent Document 1 has the following problems when controlling the equivalent series resistance to a desired value. That is, in the multilayer capacitor described in Patent Document 1, in order to control the equivalent series resistance to a desired value, the thickness of the internal resistance layer included in the terminal electrode and the material composition of the internal resistance layer must be adjusted. In other words, it is very difficult to control the equivalent series resistance.

  An object of the present invention is to provide a multilayer capacitor capable of easily and accurately controlling the equivalent series resistance, and a method for adjusting the equivalent series resistance of the multilayer capacitor.

  By the way, in a general multilayer capacitor, all internal electrodes are connected to corresponding terminal electrodes through lead conductors. Therefore, there are as many lead conductors as the number of internal electrodes, and the equivalent series resistance is reduced. If the number of laminated dielectric layers and internal electrodes is increased in order to increase the capacity of the multilayer capacitor, the number of lead conductors also increases. Since the resistance component of the lead conductor is connected in parallel to the terminal electrode, the equivalent series resistance of the multilayer capacitor is further reduced as the number of lead conductors increases. Thus, increasing the capacity of a multilayer capacitor and increasing the equivalent series resistance are contradictory requirements.

  Therefore, the present inventors have intensively studied a multilayer capacitor that can satisfy the demand for increasing the capacity and increasing the equivalent series resistance. As a result, the present inventors can connect the internal electrodes with connection conductors formed on the surface of the multilayer body and change the number of lead conductors even if the number of stacked dielectric layers and internal electrodes is the same. A new fact has been found that the equivalent series resistance can be adjusted to a desired value. Further, the present inventors can connect the internal electrode with the connection conductor formed on the surface of the multilayer body and change the position of the lead conductor in the stacking direction of the multilayer body, so that the equivalent series resistance is set to a desired value. It came to discover the new fact that it became possible to adjust. In particular, if the number of lead conductors is smaller than the number of internal electrodes, adjustment in the direction of increasing the equivalent series resistance is possible.

Thus, the first inner electrodes 41 to 44 are connected in parallel. The lead conductor 53 is formed integrally with the first internal electrode 43, and extends from the first internal electrode 43 so as to face the side surface 1 a of the multilayer body 1.

  Of the four second internal electrodes 61 to 64, the second second internal electrode 62 counting down from the second internal electrode 61 is electrically connected to the second terminal electrode 5 via the lead conductor 73. Connected. Since the second inner electrodes 61 to 64 are electrically connected to each other through the second connection conductor 9, the second inner electrodes 61, 63, 64 are also second to each other through the second connection conductor 9. Thus, the second inner electrodes 61 to 64 are connected in parallel.

As a result, the multilayer capacitor according to the third embodiment has an equivalent series resistance greater than that of a conventional multilayer capacitor in which all internal electrodes are connected to corresponding terminal electrodes via lead conductors.

  By the way, focusing on the first terminal electrode 3, the resistance component of the first connection conductor 7 is located on one side in the stacking direction with respect to the first internal electrode 43 with respect to the first internal electrode 43. The resistance component of the first connection conductor 7 is divided into the resistance component of the first connection conductor 7 positioned on the other side in the stacking direction from the first internal electrode 43. These resistance components are connected in parallel to the first terminal electrode 3. Focusing on the second terminal electrode 5, the resistance component of the second connection conductor 9 is located on one side in the stacking direction with respect to the second internal electrode 62 with the second internal electrode 62 as a boundary.

  Of the four second internal electrodes 61 to 64, the second second internal electrode 62 counting down from the second internal electrode 61 is electrically connected to the second terminal electrode 5 via the lead conductor 73. Connected. Since the second inner electrodes 61 to 64 are electrically connected to each other through the second connection conductor 9, the second inner electrodes 61, 63, 64 are also second to each other through the second connection conductor 9. Thus, the second inner electrodes 61 to 64 are connected in parallel. The lead conductor 73 is formed integrally with the second internal electrode 62, and extends from the second internal electrode 62 so as to face the side surface 1 b of the multilayer body 1.

These resistance components are connected in parallel to the second terminal electrode 5.

  Therefore, due to the difference between the resistance component of the first connection conductor 7 and the resistance component of the second connection conductor 9, the multilayer capacitor according to the fourth embodiment is compared with the multilayer capacitor C1 according to the first embodiment. Thus, the equivalent series resistance is reduced.

  As described above, according to the present embodiment, the position in the stacking direction of the first internal electrode 44 electrically connected to the first terminal electrode 3 through the lead conductor 53 and the lead conductor 73 are used. By adjusting the position in the stacking direction of the second internal electrode 62 electrically connected to the second terminal electrode 5, the equivalent series resistance of the multilayer capacitor according to the fourth embodiment is set to a desired value.
