PURPOSE: A nonpolar stacked type noise filter is provided to mount a terminal electrode of a signal side on a printed circuit board regardless of the direction of an input side and an output side by removing the polarity of the input side and the polarity of the output side of the terminal electrode of the signal side. CONSTITUTION: A nonpolar stacked type noise filter includes the first pattern sheet(10), the second pattern sheet(12), the third pattern sheet(14), the fourth pattern sheet(16), and the fifth pattern sheet(18). A conductive pattern is formed on the first pattern sheet(10). A ground pattern and a connective conductive pattern are formed on the second pattern sheet(12). A conductive pattern connected to the conductive pattern of the second pattern sheet(12) is formed on the third pattern sheet(14). A ground pattern and a connective conductive pattern are formed on the fourth pattern sheet(16). A conductive pattern is formed on the fifth pattern sheet(18). The first to the fifth pattern sheets are stacked sequentially. The conductive patterns of the first and the fourth pattern sheets(10,16) and the ground patterns of the second and the fourth pattern sheets(12,16) are connected to external electrodes, respectively. |
