Abstract:
1. A noise filter device that is inserted and connected between an alternating-current power supply and a motor drive device, the noise filter device comprising: a first substrate on which a filter input terminal, an input-side capacitor, a common-mode choke coil, and a filter output terminal are mounted; and a second substrate on which an output-side capacitor and a ground capacitor, connected between the output-side capacitor and a ground, are mounted, wherein the first substrate is selected from a plurality of first substrates, wherein the selected first substrate comprises at least one of the input-side capacitor and the common-mode choke coil having a characteristic different from an input-side capacitor and a common-mode choke coil of other first substrates, the second substrate is selected from a plurality of second substrates, wherein the selected second substrate comprises at least one of the output-side capacitor and the ground capacitor having a characteristic different from an output-side capacitor and a ground capacitor of other second substrates, and the second substrate is attached to an end of the first substrate so that the filter output terminal is electrically connected to the output-side capacitor and is substantially vertical to the first substrate.
