Features:
*Power for EMI filter is a reactive low-pass filter installed at the power inlet of electronic equipment. It can suppress noise interference transmitted through the power line of the power grid, as well as high-frequency interference signals generated by the electronic equipment itself, which can harm other electronic equipment. Therefore, for EMI has become a mandatory component in electronic devices.
*Power supply noise is a type of electromagnetic interference, with a frequency for spectrum of approximately 10kHz to 30MHz for conducted noise, with a maximum of 150MHz. According to the different propagation directions, power source noise can be divided into two categories: is external interference introduced from the power input line, and the other is noise generated by electronic devices and transmitted through the power line. This indicates that noise belongs to bidirectional interference signals, and electronic devices are both the object of noise interference and a source of noise. In terms of formation characteristics, noise interference can be divided into serial mode interference and Common-mode interference. Serial mode interference is the noise between two power lines (referred to as line to line). Common-mode interference is the noise of two power lines to the ground (referred to as line to ground). Therefore, the electromagnetic interference filter should meet the requirements of Electromagnetic compatibility (EMC), and must also be a two-way RF filter. On the hand, it should filter out the external electromagnetic interference introduced from the AC power line, on the other hand, it can also avoid its own equipment from generating noise interference to the outside, so as not to affect the normal operation of other electronic equipment in the same electromagnetic environment. In addition, the for EMI filter can suppress the series mode interference and Common-mode interference.
Precautions:
*The selection of for EMI should consider their operating voltage, current, and withstand voltage values
for EMI should be installed at the entrance of the power supply to reduce radiation interference
*The choose for EMI filter connection line is to use double wire, which can eliminate some high-frequency interference signals
* for EMI filter input and output lines should not be parallel, and a certain distance should be opened to for ensure the function of the filter
*The E-point of the for EMI filter must have good with the chassis shell and be grounded properly
