EMI/RFI Filters are electrical networks commonly used to attenuate electromagnetic interference and radio-frequency interference. They can be composed of many components such as capacitors, inductors, and resistors. One example of such a filter is the 4101-002LF, which is used in many applications. This section discusses the application field and working principle of this filter.

Application Field of the 4101-002LF

The 4101-002LF filter is designed to reduce interference on power lines by providing a low-impedance path to ground for a wide-band of common-mode interference. It is suitable for applications involving 440V AC at 60Hz. It is designed to be noise immune and is especially effective in suppressing noise signals from devices operating at high frequencies such as SMPS, home appliances, HVAC, desktops, and laptops. The attenuation is as high as 30 dB above 100KHz.

This filter is often used in motor controllers, telecommunications equipment, switching power supplies, test equipment, control equipment, and electronic assembly operations. It is particularly effective in suppressing high-frequency interference originating from high-frequency, point-source noise generators.

Working Principle of the 4101-002LF

The 4101-002LF filter consists of two main parts: a power-line filter and a common-mode noise conductor. The power-line filter is designed with ferro-resonant chokes and capacitors. These components provide a low-impedance path to ground for important power-line noise. The common-mode noise conductor is designed to provide a low-impedance path to ground for any differential-mode noise on the power line.

When a voltage is applied to the filter, the ferro-resonant chokes and capacitors create an AC voltage drop. This creates a low-impedance path to ground for interference that is outside the normal frequency range of the power line. This low-impedance path filters out high-frequency interference, which is then diverted to ground.

The common-mode noise conductor, meanwhile, provides the low-impedance path to ground for any differential-mode noise. When a differential noise signal is present, the common-mode noise conductor provides a path to ground which is lower in impedance than the power-line signal. This attenuates the voltage of the interference and allows it to be diverted to ground.

The 4101-002LF filter is of great benefit to any system that uses electrical power. It can reduce interference on power lines, resulting in better performance and more reliable operation. Its low-impedance path to ground for high-frequency interference and its common-mode noise conductor make it especially effective in suppressing point-source noise generators.
