Abstract

A multiple resonance filter includes at least three multilayer capacitors having at least two different capacitances. The at least three multilayer capacitors are adjacent each other. Two of the at least three multilayer capacitors have a same capacitance. The two capacitors with the same capacitance are on outer ends of an arrangement formed by the at least three multilayer capacitors.
