Power line filter modules provide EMI/RFI attenuation or rejection of interfering signals that are introduced onto power lines. B84144A0008R120 is a ceramic based power line filter module which is designed for global and high frequency applications, and it’s operating temperature range is -40 to +105°C. It can provide consistent, low profile and high-power filtering performance for a wide range of power levels.

The B84144A0008R120 module features a PI (π) network construction, which consists of a series inductor, a capacitive shunt and an associated connecting link between them. The inductor and capacitor are employed to attenuate the EMI/RFI signals due to the differences in frequency and phase response characteristics. In other words, when signals of the correct frequency pass through the filter, they are attenuated by the amount (attenuation) of the circuit\'s components, while other signals are rejected. This filtering action helps ensure that the power line\'s electrical signals are not disturbed by unwanted EMI/RFI signals.

The B84144A0008R120 module also employs two ferrite beads in parallel with the capacitor to further reduce any multi-frequency harmonics which might be present in the power line. These beads further reduce the EMI/RFI interference by absorbing and dissipating high frequency signals. The two beads complement the capacitive shunt to achieve optimal performance and reduce the insertion loss.

The B84144A0008R120 module also employs a frequency-dependent damping network in order to attenuate or reject a wide dynamic range of frequencies. The damping network comprises resistors, capacitors, and inductors that work together to provide a frequency-dependent response to the signal. The damping network provides a more even attenuation/rejection over a wide range of frequencies; it also helps keep the input impedance of the filter even over a wide range of frequencies, ensuring that the EMI/RFI signals are adequately filtered without creating any additional distortion.

The B84144A0008R120 module is suitable for both DC and AC power lines. It is typically used in applications with a power frequency range of 50 Hz to 400 Hz, making it ideal for global use. It is also designed for power filters in high frequency applications such as sealed switching power supplies, lighting systems, home appliances and other digital or communication systems.

The B84144A0008R120 module provides superior EMI/RFI filtering performance with low insertions loss and high signal isolation. It is an excellent choice for applications that require reliable and efficient powerline filtering to reduce conducted EMI/RFI interference.
