Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1) FIG. 1A schematically shows a laminated structure of a composite component according to a first embodiment of the present invention. 1 has a structure in which a coil 1 and a capacitor 2 are stacked. Further, the composite component of the present embodiment has three end surface electrodes 8, 8 ', 8 "on the side surface of the component.

The coil 1 has a structure in which an insulator layer 3 and coil-shaped conductor layers 4, 4 'are laminated. In FIG. 1, two coil elements 1a and 1b are formed on the left and right, respectively. The coil-shaped conductor layers 4 and 4 ′ are connected by conductors 5 through the through holes of the insulator layer 3 to form a coil. That is, one coil element 1a includes two conductor layers 4, 4 'and a conductor 5 connecting these layers.

The capacitor 2 has a structure in which a dielectric layer 6 and two electrode layers 7, 7 'are laminated. In FIG. 1, two capacitor elements 2a and 2b are formed on the left and right, respectively. Further, in FIG. 1, the conductor layer 4 'constituting the coil and the electrode layer 7 constituting the capacitor are connected by the conductor 5'. Furthermore, three end face electrodes 8, 8 ',
8 "are electrically connected to the two conductor layers 4 constituting the coil and the electrode layer 7 'constituting the capacitor, respectively. The composite component of the present embodiment configured as described above is shown in FIG. A T-type filter circuit is configured as shown in an equivalent circuit in FIG.

Hereinafter, the materials used for the composite component having the above configuration will be described.

The material of the insulator layer 3 may be a non-magnetic material or a magnetic material. Examples of the nonmagnetic material that can be used for the insulator layer 3 include an organic insulating material such as an epoxy resin / glass fiber composite material or a polyimide resin, a glass material, a glass ceramic composite material, and various ceramic materials. Any material having electrical insulation properties can be used for the insulator layer 3. When a non-magnetic material is used for the insulator layer 3, the self-resonant frequency of the coil 1 increases.

Examples of a magnetic material that can be used for the insulator layer 3 include a known magnetic material having a high magnetic permeability such as NiZn ferrite or NiZnCu ferrite. By using these magnetic materials having a high magnetic permeability for the insulator layer 3, the inductance of the coil 1 can be increased.

As the material of the conductor layers 4, 4 'and the electrode layers 7, 7', any material can be used as long as it is an electrically good conductor. In general, silver, silver-palladium alloy, copper or the like is used in consideration of the price. Is preferred.

For the dielectric layer 6, a conventionally known dielectric material made of an organic or inorganic material can be used. It is natural that the capacity of the capacitor 2 can be increased by using a material having a large dielectric constant for the dielectric layer 6. Further, by changing the area of the electrode layers 7 and 7 ′ constituting the capacitor 2 and the thickness of the dielectric layer 6, the capacitance of the capacitor 2 can be changed even when the same material is used.

As the material of the end face electrode 8, any conductive material generally used for an end face electrode of an electronic component can be used. Generally, it is desirable that the material used for the end face electrode of the electronic component is not a single material but is composed of a plurality of layers. Specifically, the end face electrode of the composite component of the present invention is composed of an underlayer made of silver, a silver-palladium alloy, copper or the like, a nickel plating layer, and an outermost layer made of tin or an alloy thereof. However, this configuration is merely an example, and another metal or organic material such as a conductive resin may be used for the end face electrode 8.
Can also be selected as one of the constituent materials.

As an example of using the composite part of the present invention,
The composite component of the present invention may be mounted on a ceramic substrate such as alumina or ferrite on which a wiring pattern is formed in advance by using a high-temperature firing paste. In this case, it is necessary to impart heat resistance enough to withstand the firing temperature to the material of the end face electrode 8.

The above-described embodiment of the present invention shows one minimum required structure of the composite part according to the present invention. That is, by increasing the number of the insulator layers 3 and the conductor layers 4 constituting the coil 1 in the above configuration, the number of turns of the coil 1 can be increased and the inductance can be increased. Similarly, the capacitance of the capacitor 2 can be increased by repeating the combination of the dielectric layer 6 and the electrode layers 7, 7 'constituting the capacitor 2 to form a laminated structure. In this case, the electrode layers 7, 7 ', 7 ", 7"'
It is natural that the electrodes are alternately taken out from... And connected to the conductor 5 ′ and the end face electrode 8 ″, respectively.

Further, as shown in FIG. 2, in order to improve the electric characteristics of the coil 1, insulating layers 9, 9 'made of a magnetic material are laminated on the upper and lower surfaces of the coil 1 to improve the coil characteristics. be able to. As shown in FIG. 3, a surface layer made of an insulator or a dielectric is provided on the upper and lower surfaces of the coil 1 and the upper and lower surfaces of the capacitor 2 for the purpose of improving the mechanical strength of the composite component and adjusting the dimension in the thickness direction of the composite component. It is also possible to form an intermediate layer 10 "consisting of 10, 10 'or an insulator or a dielectric. A thick insulator layer 9' or an intermediate layer 10" is inserted between the coil 1 and the capacitor 2 for the above purpose. In such a case, when forming the conductor 5 ′ connecting the conductor layer 4 ′ of the coil 1 and the electrode layer 7 of the capacitor 2, sufficient care such as increasing the diameter of the through hole is required.

One of the important electrical characteristics of an LC composite component for noise reduction, particularly a T-type or π-type filter, is a filter cutoff frequency. The cutoff frequency of the filter is defined as a frequency at which a predetermined amount of attenuation is obtained, and is determined by the inductance of the coil 1 and the capacitance of the capacitor 2. As can be understood from the above description, the composite component according to the present invention can easily change the inductance of the coil 1 and the capacitance of the capacitor 2, so that a filter having a cutoff frequency over a wide frequency range can be easily manufactured. .

Further, since the composite component of the present invention has a structure in which a plurality of coils and a plurality of capacitor elements are formed in the same lamination plane, it is easy to produce differently from the conventional lamination type. It has a feature that various types of LC filters can be separately formed by a slight change such as a change in a printing pattern.

In the above description, a composite component having the shape of a surface mount component in which an end face electrode is formed directly on the end face of the component has been described.

When the coil 1 and the capacitor 2 are made of a ceramic material, a firing step is required in addition to the above steps. Hereinafter, a detailed manufacturing method when the coil 1 and the capacitor 2 are made of a ceramic material will be described.

The insulator layer 3 and the dielectric layer 6 can be formed by a green sheet molding method, a printing method, a dipping method, a powder molding method, a spin coating method, or the like. Conductor layer 4,
The 4 ', the electrode layers 7, 7' and the end face electrodes 8, 8 ', 8 "are usually formed by a printing method, but may be formed by a pattern forming method using a laser, a transfer method, a dropping method, a thermal spraying method, or the like. It can be formed using means.

The firing temperature range of the composite part is 800 ° C. to 13
It is in the range of 00 ° C. The conductive material that can be used changes depending on the firing temperature. For example, when silver is used as the conductor material, the firing temperature of the composite component is limited to about 900 ° C. When a silver-palladium alloy is used as the conductor material, the composite component can be fired at 950 ° C. If it is necessary to fire composite parts at higher temperatures, nickel
It is necessary to use palladium or the like.

When the composite component of the present invention is manufactured using the above ceramic material, the composite component may be fired after all the constituent materials are laminated, or the coil 1 and the capacitor 2 may be fired separately. Later, coil 1 and capacitor 2
