Abstract
A concentrated constant type delay device can be assembled in simple steps and has simple and stable structure. The delay device comprises a composite capacitor which comprises a common electrode placed on one surface of a dielectric and a plurality of separated electrodes placed on the other surface of the dielectric and the separated electrodes being respectively connected to each joint of coils connected between an input terminal and an output terminal.
Claims4
A concentrated constant type delay device comprising:
- a substrate;
- an input terminal, an output terminal and a common terminal mounted on said substrate;
- a plurality of coils connected in series between said input terminal and said output terminal and having a joint between adjacent coils;
- a plurality of capacitors, equal in number to the number of said joints, each connected between said common terminal and a different one of said joints;
- wherein said plurality of capacitors is formed as a composite capacitor having a dielectric with a common electrode on one surface and a plurality of separated electrodes on the opposite surface, said common electrode having two leads extending therefrom in one direction and said separated electrodes each having one lead extending therefrom in the said one direction and each of said leads of said separated electrodes being connected to a joint;
- wherein one of said leads of said common electrode is passed through said substrate to form said common terminal.
