Power Line Filter Modules

Power Line Filter Modules provide superior filtration of interference generated on mains power cables in order to retain electrical signal integrity and provide enhanced performance. B84143B1250S081 is a Power Line Filter Module from EPCOS, designed to reduce ripple noise and interference caused by mains power cables.

Application Field

B84143B1250S081 is designed for industrial applications including off-line AC motor drives and switching power supplies, as well as power line communication and data transmission systems. When connecting electrical devices to mains power cables, this filter can provide an effective solution for reducing ripple noise and interference, ensuring that signal integrity is maintained.

Working Principle

B84143B1250S081 works on the basis of inductor-capacitor-capacitor (LCC) filtering technology. It has a common mode inductor, a differential mode capacitor and a differential mode inductor. The common mode inductor blocks high-frequency noise from the mains power cable, while the differential mode inductor and capacitor form an LC resonance circuit which attenuates noise on the power lines. In addition, the filter also has a damping resistor to further reduce the amplitude of interference.

This Power Line Filter Module is also designed to operate in a wide temperature range of -40°C to 130°C, making it suitable for industrial applications. The attenuation band of the filter is from 400 kHz to 100 MHz, ensuring effective noise filtration. The actual frequency range may vary depending on the filter\'s electrical characteristics.

B84143B1250S081 is also designed for easy and reliable mounting. The filter contains two mounting pins for easy installation and is enclosed in a plastic housing, providing electrical and mechanical protection from outside influences. It is also designed to be compliant with RoHS and REACH regulations.

B84143B1250S081 is a highly effective Power Line Filter Module which provides superior filtration of interference generated on mains power cables. It is designed for industrial applications such as off-line AC motor drives and switching power supplies, as well as power line communication and data transmission systems. The filter works on the basis of LCC filtering technology, and has a wide temperature range of -40°C to 130°C. Given its easy and reliable mounting, high attenuation and compliance with RoHS and REACH regulations, B84143B1250S081 is an ideal choice for industrial power line filtering.
