Title:
Capacitive devices, resonant circuits and electronics
Document Type and Number:
Japanese Patent JP6319758
Kind Code:
B2
Abstract:
The present disclosure is to improve electric characteristics in a capacitance device (device) including capacitors connected in series in a direction in which internal electrodes are laminated. Three capacitors are formed by dielectric layers (3) and four internal electrodes (30 to 33) laminated via the dielectric layers (3). The internal electrodes (30 to 33) each have an electrode body forming a capacitance, and centers of gravity of these electrode bodies are aligned on an axis formed by a straight line extending in the lamination direction. A device includes two variable capacitance units (40 and 41) each including the capacitors connected in series in the lamination direction, and external terminals formed on lateral surfaces of a variable capacitance device body (2). The axes of the variable capacitance units (40 and 41) are arranged in parallel with each other. A current flows in opposite directions in the two adjacent capacitance units.
