Module design features:
1. First level differential mode filtering, two differential inductors, used for differential mode filtering of AC power supply, to suppress mid to high frequency interference
2. First level common mode filtering, combining x2 capacitors and common mode inductors to form common mode filtering
3. Triple common mode filtering, due to the use of two-stage (also known as two-stage) filtering, has a good effect in filtering out noise. Can effectively suppress the problem of fast transient group pulse interference with repetitive frequencies of several thousand for hertz at certain user sites
Main parts selection:
X2 capacitor: 0.22UF 3PCS
Y2 capacitor: 275V 3300PF 2PCS
Differential mode inductance: 47UH 2PCS
Common mode inductance: 2PCS
Resistance: 1PCS
Socket: 7.62 2PIN, 3PIN, 1 PCS each
The three-level composite (1-level differential) mode+2-level common mode) EMI electromagnetic interference filtering circuit has a good filtering effect on noise due to the use of three-level (also known as three-level) filtering. It can effectively suppress the problem of rapid transient group pulse interference with repetition frequencies of several thousand for hertz at certain user sites.
This module, when used in conjunction with a decoder or power amplifier, can filter out the DC component of the power supply, eliminate and suppress transformer buzzing and high-frequency noise in the power supply, purify the power supply, and significantly improve the sound quality of the power supply. Power amplifier enhances resolution and quiets the background.
The input GND needs to be connected to the ground wire of the power cord or to the chassis casing, depending on the specific situation.

Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
