、該シ回路から遮蔽していた。When multiple electrical components are mounted on a single board and then mounted on a printed circuit board as a composite electrical component with a certain function, undesirable electrical connections may occur between the electrical components and other electrical circuits on the printed circuit board. Many connections occur. Conventionally, in order to eliminate this undesirable electrical coupling, a shield case made of metal such as aluminum was placed over the composite electrical component to shield it from the circuit.

まう。However, providing a shield case for each individual composite electrical component not only increases cost but also extremely poor productivity. Furthermore, when attempting to downsize a composite electrical component by mounting surface mount components and configuring the composite electrical component, the existence of the shield case makes miniaturization of the composite electrical component ineffective. Put it away.
本発明はシールドケースを必要とせずにそれ自身で遮蔽
能力を有する廉価な複合電気部品を提供することを目的
とする。It is an object of the present invention to provide an inexpensive composite electrical component that has its own shielding ability without requiring a shielding case.

くなる。When the composite electric component is attached to a printed circuit board, by using the ground plane of the printed circuit board, the electric component can be almost surrounded by a conductor having a ground potential, increasing the shielding ability between it and other circuits. be able to. Therefore, the conventional shield case is no longer necessary.
