USB Filter Board USB anti-interference filter board Noise Eliminator for Power Amplifier PC USB Power purification

USB Power Filter Board Noise Eliminator for Amplifier PC Power purification

1. Use 1000UF filter capacitor;
2. By the coil constitute a capacitive filter circuit, than the simple use of capacitor filtering better;
3. With power indicator.

In the DIY small amplifier often encounter power amplifier board noise situation, especially when using the computer USB power supply situation is more serious, the speaker can hear the noise of Zizi. This situation may be caused by poor power supply noise or stray electromagnetic interference.

This filter board using 1000UF filter capacitor + inductor combination than the simple use of capacitors to effectively remove the interference, give you a pure music world.

USB anti-interference USB power purification board, designed specifically for USB 5V power supply of small power amplifier board, the input voltage can not be higher than 6V.

PCB size: 47MM x 27MM x17MM (LxWxH)

This board input is female USB port , the output USB female, this board can be connected to the computer USB, but also play a role in purifying the USB power supply ripple. (Note: only USB to take the signal and power, 2P terminal only take the power)

Please note before buying:

1. The filter board can only filter the power caused by the noise, the sound of the existing noise can not do anything.
2. The use of power amplifier board environment is different, so this filter board can not guarantee that will be able to remove the interference. After all, there may be other interference factors.
