Product description:
The power supply EMI filter is a reactive low-pass filter, which is installed at the power inlet of electronic equipment. It can not only suppress the noise interference transmitted through the power line of the power grid, but also inhibit the high-frequency interference signals generated by the electronic equipment itself from being connected to the power grid, endangering other electronic equipment. Therefore, EMI has become a device that must be installed in electronic equipment.
Power supply noise is a kind of electromagnetic interference, and its frequency spectrum of conducted noise is about 10kHz~30MHz, up to 150MHz. According to the different propagation directions, power supply noise can be divided into two categories: one is the external interference introduced from the power supply incoming line, and the other is the noise generated by electronic equipment and transmitted through the power supply line. This shows that noise belongs to bidirectional interference signal, and electronic equipment is both the object of noise interference and a noise source. In terms of formation characteristics, noise interference can be divided into two types: 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 shall meet the requirements of electromagnetic compatibility (EMC), and it must also be a bidirectional RF filter. On the one hand, it shall filter out the external electromagnetic interference introduced from the AC power line, and on the other hand, it can avoid its own equipment from emitting noise interference to the outside, so as not to affect the normal operation of other electronic equipment under the same electromagnetic environment. In addition, the EMI filter can restrain the series mode interference and common mode interference.
 
matters needing attention:
The selection of EMI filter shall consider its working voltage, working current and withstand voltage value
EMI filter shall be installed at the power inlet to reduce radiated interference
It is better to select double glue line as the connection line of EMI filter, which can eliminate some high-frequency interference signals
The input and output lines of the EMI filter must not be parallel. A certain distance must be extended to ensure the function of the filter
The E point of the EMI filter must be in good contact with the chassis shell, and the grounding wire must be connected

Description：
Power EMI filter is a kind of reactance low-pass filter, installed in the power inlet of electronic equipment, both to suppress the noise interference transmitted through the power line of the grid, but also to suppress the high-frequency interference signal generated by the electronic equipment itself into the grid, endangering other electronic equipment. Therefore EMI has become the electronic equipment must be installed in the device.
Power noise is a kind of electromagnetic interference, the spectrum of the conducted noise is roughly 10kHz ~ 30MHz, up to 150MHz. according to the direction of propagation, the power supply noise can be divided into two categories: one is introduced from the power line into the external interference, the other is generated by the electronic equipment and the power line conducted out of the noise. This shows that the noise is a two-way interference signal, electronic equipment is both the object of noise interference, but also a noise source. If you look at the formation characteristics, noise interference is divided into series mode interference and common mode interference two. Series-mode interference is the noise between two power lines (referred to as line-to-line). Common mode interference is the noise between two power lines to the earth (referred to as line-to-ground). Therefore, EMI filters should meet the requirements of electromagnetic compatibility (EMC), and must also be bi-directional RF filters, on the one hand to filter out external electromagnetic interference introduced from the AC power line, on the other hand, can also avoid their own equipment to the external noise interference, so as not to affect the normal work of other electronic equipment in the same electromagnetic environment. In addition, the electromagnetic interference filter on the series mode, common mode interference are to play a suppression role.
 
Precautions：
EMI filter selection should consider its operating voltage, operating current, withstand voltage value
EMI filter should be installed at the power supply entrance position to reduce radiation interference
EMI filter connection line use double rubber line for good, it can eliminate part of the high frequency interference signal
EMI filter input and output lines should not be parallel, need to pull away a certain distance to ensure the function of the filter
EMI filter E point and chassis shell must be in good contact, and connected to the earth wire
