Abstract:
A multilayer filter comprising:a multilayer body formed by stacking and sintering dielectric and conductive layers;input-output terminal electrodes overlaid on two respective edge faces of the multilayer body;ground electrodes overlaid on two opposed sides of the multilayer body separated from each other by a distance W;inductance elements, each inductance element including a respective through-hole electrode of diameter d formed in a corresponding through-hole in said multilayer body;paralleled capacitors connected to said inductance elements and formed in said multilayer body; andwherein one end of each inductance element is electrically coupled to said input-output terminal electrode, the other end of each inductance element being connected to a conductive layer formed as a sealed electrode in said multilayer body; anda ratio W/d of the diameter d of each through-hole electrode to the distance W separating the ground electrodes being not less than 1.6 and not greater than 11.4.
