Three-Terminal Filter

A three-terminal filter (e.g., three-terminal capacitor or EMI filter) is commonly used for noise suppression in power lines.

• Pins: Input, Output, Ground
• Function: Reduces high-frequency noise
• Typical Use: Power supply input filtering
• Example Part: TDK Corporation's μI-cap (e.g., MMZ series)

Note: Mount close to the noise source or IC power pin for best performance.
