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.

A resonance filter, comprising:
- at least three multilayer capacitors having at least two different capacitances, the at least three multilayer capacitors being adjacent to each other;
- wherein two capacitors of the at least three multilayer capacitors have a same capacitance, the two capacitors being on outer ends of an arrangement formed by the at least three multilayer capacitors;
- wherein the at least three electrode multilayer capacitors comprise a stack of dielectric layers;
- and electrode layers in the stack, the dielectric layers and the electrode layers forming a component;
- wherein external contacts on faces of the component correspond to electrode layers in the component;
- wherein the capacitors, the inductance of the electrode layers and of the external contacts, from LC filters.
