SURFACE-MOUNTED PASSIVE ELECTRONIC COMPONENTS, AND STRUCTURE AND METHOD FOR MOUNTING THEM

WIPO Patent Application WO/2005/062464

A1

When a multilayed LC filter (1) is forward mounted on a mounting board, an adjustment capacitor (C4) constitutes a resonator (Q1) on the input side in conjunction with an LC parallel circuit comprising a resonance capacitor (C1) and a resonance inductor (L1). An adjustment capacitor (C6) constitutes a resonator (Q2) on the output side in conjunction with an LC parallel circuit comprising a resonance capacitor (C2) and a resonance inductor (L2). However, when the multilayed LC filter (1) is rotated by 180 degrees, reversed left to right, and then mounted on the mounting board, an adjustment capacitor (C5) constitutes a resonator (Q1) on the input side in conjunction with the LC parallel circuit comprising the resonance capacitor (C2) and the resonance inductor (L2). An adjustment capacitor (C3) constitutes a resonator (Q2) on the output side in conjunction with the LC parallel circuit comprising the resonance capacitor (C1) and the resonance inductor (L1).
