The 5500.2273 power line filter modules are primarily designed to provide quality filtering of conducted emissions from electronic equipment that strive to meet the rigorous conducted emission limits. The 5500.2273 is a three-order lowpass filter designed to reduce the amount of conducted emissions on the mains supply line to the electronic equipment. It utilizes a combination of capacitive and inductive elements connected in a series-notch topology.

The module is composed of three independent stages connected in series. It is designed to offer a typical attenuation of attenuator of up to 45dB across the frequency range from 10 to 500MHz. The three stages are made up of a combination of low-inductance capacitors, ferrite beads, and ferrite beads terminated with inductors. Each stage provides a high-impedance at the operating frequencies and a low-impedance at higher frequencies.

The first stage of the 5500.2273 module consists of two low-inductance capacitors connected in series and a ferrite bead. The capacitors have low ESL values and provide a high impedance at frequencies below 10MHz. The ferrite bead provides damping at higher frequencies and helps to reduce the high-frequency noise propagating on the line. The second stage consists of two ferrite beads connected in series. The ferrite beads help to reduce the propagated noise on the line and provide a balance between the capacitors and primary inductors.

The third stage of the module consists of two primary inductors connected in series and two low-inductance capacitors connected in parallel. The primary inductors reduce the amount of conducted noise in the frequency range of 10 to 500MHz. The capacitors provide a high impedance at this frequency range while still allowing a low-impedance at higher frequencies. The mix of components allows the module to provide the desired attenuation at the desired frequency range.

The module can be used in various applications such as EMI/EMC filtering, noise reduction, and power line isolation. It is commonly used in process control systems, energy metering applications, and consumer electronics. It is available in a variety of case material and size options to meet the requirements of different applications.

The 5500.2273 power line filter module is a robust, compact, and cost-effective solution for noise reduction and EMI/EMC filtering. Its low-inductance capacitors, ferrite beads, and primary inductors provide excellent performance for applications requiring low noise and EMI/EMC compliance. It provides a balanced attenuation between 10 to 500MHz and is available in a variety of sizes and materials to meet the needs of various applications.
