Title:
LAMINATION LC FILTER ARRAY
Document Type and Number:
Japanese Patent JP2018064204
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lamination LC filter array in which the parasitic inductance of a first capacitor is equivalent to that of a second capacitor.SOLUTION: A lamination LC filter array FA1 includes a filter F1 having an inductor L1 and a capacitor C1, and a filter F2 having an inductor L2 and a capacitor C2. Terminal electrodes 11, 12 are connected with the inductor L1. Terminal electrodes 13, 14 are connected with the inductor L2. Terminal electrode 15 is connected with the capacitors C1, C2. Terminal electrode 15 is placed in the center of the first principal surface 1a of an elementary body 1. When viewing from a direction perpendicular to the first principal surface 1a, the terminal electrodes 11, 12, 13, 14 are arranged at different corners of the elementary body 1.SELECTED DRAWING: Figure 2
