The FN351-110-35 is a power line filter module used to reduce the amount of noise and interference on power lines. This device is designed to reduce conducted and radiated emissions from the power lines in order to meet the emission requirements of various safety standards and regulations. The FN351-110-35 is typically used in industrial and commercial applications, where noise on the power line can cause problems such as equipment malfunctioning or data corruption. In addition, the device can be used to provide additional protection against lightning and surges.

The FN351-110-35 consists of two main components, an inductor filter and a capacitor filter. The inductor filter is composed of two inductors, which are connected in parallel and placed in a common-mode configuration for the suppression of common-mode noise. The capacitor filter is composed of two capacitors, connected in parallel and placed in a differential-mode configuration for the suppression of differential-mode noise. The inductors and capacitors are connected in series to the power line and grounded at each end, forming a low-pass filter that significantly reduces the high-frequency noise that can interfere with signals. Additionally, the device has two additional capacitors that are connected in parallel to the power line but have no connection to ground. These capacitors provide extra protection from high voltage surges.

The FN351-110-35 works by filtering out a wide range of frequencies that are commonly found on power lines. By suppressing these frequencies, the device reduces the amount of harmful interference and enables other electrical equipment to work more reliably. The inductors and capacitors that make up the device act like a band-pass filter that only passes frequencies below the cut-off frequency (defined by the component values) while blocking frequencies above it. Additionally, the inductors and capacitors also effectively dampen fluctuations in the power line voltage that can cause electrical equipment to malfunction.

The FN351-110-35 is a cost-effective solution for reducing high frequencies on power lines. This makes it suitable for industrial and commercial applications, where reliability and product safety are of utmost importance. The device is capable of filtering out a wide range of frequencies and is able to handle high voltage surges and transients, making it an ideal solution for applications where noise and power surges can cause equipment malfunction.
