構成している。Conventionally, in intermediate frequency transformers used in radios, etc., a cylindrical capacitor ψ) is attached to the bottom surface of the base of the coil bobbin ←), as shown in Figure 1.
The coil is housed in a shielded casing (9).
しかし乍ら、近年、電子部品の小型化や薄型化が進むに
つｎて筐体全体の閤さを低くする必要が生じ、従来のよ

連した要望を満たすことができなかった。However, in recent years, as electronic components have become smaller and thinner, it has become necessary to reduce the overall stiffness of the housing, and conventional cylindrical capacitors are too large to fit inside the housing. It was not possible to incorporate the system into the system, and it was necessary to install it externally, so the repeated requests could not be met.
本発明はこのような問題点を解消するために。The present invention aims to solve these problems.
コイルのボビンの一部に［極を形成して筐体内に衷ンデ
ンサを構成した複合電子部品を提供するものである。The present invention provides a composite electronic component in which a pole is formed on a part of the bobbin of a coil and a capacitor is configured within the housing.
本発明の実施例を図面について説明すると。An embodiment of the present invention will be described with reference to the drawings.

The capacitor can easily be placed in the desired valley by

In Figure 4, an insulator (Ill) is riveted around the lower end of the coil bobbin (3), and a conductor electrode +5 (5) is fixed to a part of the upper and lower surfaces of this insulator (B) to form a capacitor. The lower electric wound (5) is placed in close contact with the coil bobbin base (8) to which the terminal (9) is attached. The poles (5) (1) are fixed to the upper and lower surfaces, and the coil bobbin base (8) is used as an insulator for the capacitor.
