Title:
FILTER CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/181606
Kind Code:
A1
Abstract:
This filter circuit comprises a resonance circuit, the resonance circuit including an inductance element and a capacitor. The capacitor comprises an element stack, an exterior body, a first external electrode and a second external electrode, and a third external electrode. The element stack is composed of a stack of a plurality of capacitor elements. In a first capacitor element, a first end portion is electrically connected to the first external electrode. In a second capacitor element, a first end portion is electrically connected to the second external electrode. The third external electrode is electrically connected to the cathode portions of the capacitor elements. The configuration provides a filter circuit enabling a decrease in the number of capacitors.
