<p>PROBLEM TO BE SOLVED: To provide a small box type noise filter with reduced influence of the heat generated from the filter on X- and Y-capacitors and no metal part is exposed outside the case to which a voltage from input/output terminals is applied. SOLUTION: The filter comprises coils and capacitors as constituent components all housed in a box type case and has input/output terminals and screw terminals bored type an insulation board at specified positions. X- capacitors 13 are disposed on one surface of this board and coils 15 disposed on the other surface. The terminals of the capacitors 13 and coils 15 are connected to the screw terminals to form a noise filter circuit with the screw terminals used for input/output terminals 11.</p> |
