■Noise filter (power supply line filter)
A noise filter is effective for reducing radiated noise in the band up to 10 MHz.
For the noise filter, use a HF3010C-SZA from Soshin Electric Co., Ltd. (or a noise filter with equivalent performance).
• Do not bundle the cables on the input side and output side of the noise filter. If bundled, the noise on the output side is
induced into the filtered cable on the input side.
