Power Line Filter Modules

The commonly used power line filter modules are FN3280H-120-35, which are mainly dividing current components according to their application fields and working principle.

The FN3280H-120-35 filter module, which is classified as a power line filter module, has a wide application range in electronic and electric drives. As a power line filter, it is mainly used to absorb and filter the high-frequency noise of electronic and electric control systems. The module complies with UL, CSA and VDE standards, which can ensure safe and reliable operation,and meet high quality requirements.

In terms of working principle, the FN3280H-120-35 module is composed of two parts. First, the low-pass filter part contains three inductors connected in series, and two capacitors connected in parallel. This low-pass filter reduces the current high-frequency noise and then transmits to the subsequent components. Second, the common mode inductor is connected in series with the low-pass filter to reduce the common-mode interference, thus improving the practical safety of the filter. By adding this common-mode inductor, the common-mode noise attenuation will improve two times.

Apart from its noise absorption and filter, FN3280H-120-35 provides high-quality filtering performance with low harmonic distortion and strong anti-interference capability. It also reduce power consumption and improve the working efficiency.

In conclusion, FN3280H-120-35 is classified as a power line filter module. It has a wide application in electronic and electric drives. With a low-pass filter and common-mode inductor, it effectively reduce high frequency noise and common-mode interference and provide high-quality filtering performance without harmonic distortion.
