Power Line Filter Modules are designed to condition incoming AC power to desirable output. B84142J0180S081 is one model from EPCOS AG and belongs to the B841 series.

Application Field

The B84142J0180S081 module is used in a variety of applications, most commonly in industrial inverters, electric motors, robotics, electromechanical systems, medical devices, power supplies, frequency converters and power conditioners. It is a Type 1, Class A filter module as specified by EN/IEC 61800-3, and is rated for 250 V and 16 A operating current. The module offers high tolerance to electromagnetic interference (EMI) and excellent power supply current filtration, providing a reliable and efficient power conditioning solution. The total attenuation of the module is >20 dB, with a 3dB cut off point of 32MHz.

Working Principle

The B84142J0180S081 module consists of three inductors, which are arranged in a three-phase delta connection. The electric bias of the inductors causes a steep transition between them, providing a high cut-off frequency and high attenuation. In addition, the module includes three capacitors, which act as high frequency filters, and two X capacitors, which offer low frequency filtering. All components are arranged in a compact, vibration and noise-resistant housing, ensuring long-term reliability and durability.

The module works by blocking unwanted frequencies, such as noise and spikes, while allowing the desired frequencies to pass through. By providing an effective low pass filter, the module provides clean incoming power, free from interference and noise, and minimizes the risk of overload or short circuits. The module also reduces harmonic distortion, helping to extend the life expectancy of components.

By providing a stable power environment, the B84142J0180S081 helps to ensure reliable operation of the load, reduce maintenance needs, and improve overall system performance. The module is also easy to install, making it suitable for a wide range of applications.
