できない。 Active filters are constructed from a combination of active elements such as resistors, capacitors, and transistors. One example is shown in FIG. resistance,
The capacitor and active element are mounted on the printed wiring board and wired appropriately. Conventionally, a composite capacitor in which a plurality of capacitors C 1 , C 2 , C 3 , and C 4 are formed by alternately laminating dielectric layers 5 and electrode layers 6 as shown in FIGS. 1 and 2 is used. external terminals 1, 1', 2, 2',
3, 3', and 4, 4' have been proposed. To attach this to a printed wiring board, attach it to a specified location on the printed wiring board in the flat position shown in the figure, and then connect terminals 1 to 4 with solder. , 1' to 4' are connected to the ends of the corresponding printed conductors. but,
If a flat plate type capacitor is mounted flat, it will occupy a large amount of the surface of the printed wiring board, so even if the composite capacitor is small, it is not possible to sufficiently increase the packaging density.

非常に上がる。 The present invention uses the surface of the composite capacitor itself as a mounting board for resistors and active elements, and uses only one side of the periphery of the composite capacitor to form an external terminal for connection to an external circuit. A feature is that the external terminals are formed in two rows on this side. This allows the active
Since the filter can be attached to the printed wiring board in a plate-like state, the mounting density is greatly increased.

れている。 FIG. 3 shows the active filter of the present invention, in which a composite capacitor 7 having a plurality of electrodes inside a dielectric material as shown in FIGS. 1 and 2 is prepared. Unlike the case shown in FIGS. 1 and 2, in the present invention, the connection terminals to the external circuit are gathered on only one side 8 of the plate-shaped composite capacitor 7, and the connection conductor 9 for internal connection is gathered on the other side. , 10, 11 are formed. These connection conductors are connected to the electrode lead-out portion and also to the wiring pattern 12 provided on the surface of the composite capacitor 7. Resistors 19, transistors and
Active elements 13 and 14 such as IC chips are mounted,
It is connected to the wiring pattern 12 by solder. Two rows of external terminals 15 and 16 are baked onto one side 8 of the composite capacitor 7. These external terminals serve as connection terminals to the printed wiring board on which the active filter of the present invention is to be mounted, and are connected to lead-out conductors from predetermined positions of the internal circuit.

できる。 The active filter configured as described above is mounted at a predetermined location on the printed wiring conductor of the printed wiring board 17 so that the surface of the active filter and the surface of the printed circuit board are perpendicular to each other as shown in FIG. Connect columns 15 and 16 to corresponding printed wiring conductors. At this time, temporary attachment means such as adhesive may be used, or insertion holes may be formed in the printed circuit board, and the sides with the terminal rows 15 and 16 may be inserted into the insertion holes. With the configuration of the present invention, all the connection terminals for external circuits are gathered on one side of the flat element, so it can be mounted vertically on the printed circuit board, which improves the efficiency of use of the printed circuit board surface. can be increased significantly.
