TPA3251 Dual-Channel Stereo Digital Power Amplifier-175W*2, All-Aluminum Build

 

product details:

1. Using original TPA3251D2

2. The main filter electrolytic capacitor adopts imported famous brand

capacity 330UF/100V*4, which guarantees strong and continuous power

support.

3. High-precision chip resistors are selected for the resistors to ensure a good signal-to-noise ratio of the whole machine.

4. Use special inductance for audio to ensure the sound is clear and powerful.

5.PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tinning process to ensure good passing performance of large and small currents. First-class PCB quality.
