The supply of fever capacitors is unstable, and the capacitors will be sold with different brands when shipped. The pictures just for reference only.

Features:

1) The rectification part adopts 4 independent rectifier diodes, and each diode has an anti-interference capacitor in parallel, which can prevent the useful signal (usually high frequency signal) and the power frequency signal (50Hz), Mutual modulation is generated on the rectifier diode. Thereby generating an interference signal, interfering with the normal operation of the machine. eliminating the "modulated hum", and eliminating the interference source from the root cause for the next circuit.

2) PCB LAYOUT design, the entire circuit board is grounded at one point. Even if multiple devices and lines share a power board, no power ground loop will be generated. Without a ground loop, no hum will be generated. Solve the ground loop problem from the source.
