KDBYT 18A High Frequency AC Power Filter EMI Filter Module Anti-Jamming DIY for Speaker Audio Amplifier Home Theater
$474.62
Name: Two-pole hybrid EMI power filter.
Specifications: 18A high current common mode inductor.
PCB size: 95X28X1.6MM.
The input GND needs to be connected to the ground of the power cord and can be connected to the chassis.
The following are some common sense of high frequency electromagnetic interference EMI.
For high-frequency electromagnetic interference (EMI), generally three technologies can perform power supply filtering to suppress interference noise. In actual use, it is often mixed with two or even multiple technologies. :
1. Add a capacitor between the live and neutral wires of the power supply, that is, the X capacitor. X2 type is selected, the main function is to eliminate common mode interference, and the capacity range is 0.01UF—0.47UF.
2. Add a capacitor between the power line and the ground, that is, the Y capacitor. Select Y2 type, mainly to eliminate crosstalk interference, the capacity range is 2200pF ~ 0.1μF. In order to reduce the leakage current, the capacitance should not exceed 0.1μF, and the board is 3300PF.
3. Common mode rejection, common mode inductance (suppression coil on two power lines), when the rated current is large, the wire diameter of the common mode choke should be increased accordingly, so as to withstand large current. In addition, the proper increase in inductance can improve the low-frequency attenuation characteristics. This circuit uses 10MH.
