Power Line filter modules are used to protect sensitive electronic devices from electromagnetic interference (EMI). These filters are designed to reduce interference by blocking or absorbing unwanted signals that can be conducted along the power lines.

The FN256-80-34 circuit is a power line filter module designed for use in applications where high-frequency EMI noise must be reduced. It consists of two main components: a low pass filter and an EMI suppression box.

The low pass filter is composed of two capacitors and an inductor. It is designed to eliminate signals from the power line above a certain frequency. The filter has a cut-off frequency of 6MHz, so any signal frequencies above that are blocked. This filter is also designed to filter out harmonics up to the 30MHz range, making it ideal for use in USB, Ethernet, and other digital interfaces.

The EMI suppression box is a shielded metal box containing three different types of ferrite beads. These beads absorb electromagnetic energy and attenuate common-mode interference. They are arranged in such a way that they form an effective shield against both common-mode and differential-mode EMI noise.

The FN256-80-34 is designed for use in a wide range of applications, such as computers, medical equipment, consumer electronics, and industrial systems. It is also suitable for applications where EMI noise is high, such as in areas near broadcast towers or close to power lines. The FN256-80-34 is an effective and affordable solution for reducing EMI noise and interference.
