Power line filter modules are used to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) in various applications. The NAH-16-681 filter module is an EMI filter designed to protect sensitive electronic circuits from unwanted interference that may be induced onto power lines by devices such as charge pumps or RF transmitters. The filter module is suitable for use in a wide variety of circuits and applications, from hobby robotics to medical device manufacturing.

The NAH-16-681 filter module is a shielded module with a four-stage filter element. The filter element consists of four distinct stages: a common mode inductor, a differential mode inductor, a DC blocking capacitor, and a common mode filter capacitor. The common mode inductor passes AC frequencies while blocking DC currents. The differential mode inductor blocks AC frequencies while letting DC currents pass through. The DC blocking capacitor prevents DC current from passing through the filter element. Finally, the common mode filter capacitor provides additional filtering for high frequency signals.

The NAH-16-681 filter module is designed to filter out EMI/RFI signals in the 2-500MHz range, allowing signals in this range to pass through while suppressing those outside this range. The module reduces common mode noise up to 43dB in this frequency range, while providing up to 13dB of differential mode attenuation. The module is designed to withstand temperatures ranging from -40°C to 85°C, ensuring reliable operation in a variety of environments. The module can mount directly to a printed circuit board or be attached using a 50-ohm SMA coaxial connector.

The NAH-16-681 filter module is an excellent choice for applications requiring noise suppression in the 2-500MHz range. The module\'s four-stage filter element ensures high levels of EMI/RFI suppression in this frequency range. The module is also designed for low temperature and high current operation, making it suitable for use in a wide variety of applications. This makes it a great choice for applications such as hobby robotic projects, medical device manufacturing, and other sensitive electronic circuits.
