ขาย Tpa3116 2.0 บอร์ดขยายเสียงดิจิตอลคู่ชิป Wima (100W + 100W) ราคาที่ดีที่สุด

Use original TPA3116 chip *2 Coupling s are used in Germany WIMA 1uF The main circuit of the electrolytic signal adopts ELNA680uF/35v*2 imported from Japan to ensure strong and continuous power support. The resistor uses a 1% chip resistor to ensure a good signal-to-noise ratio. The PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of tin-spraying ensures the good passing performance of the current. The special inductor of the iron silicon aluminum power amplifier is used to ensure the sound is crisp and powerful.
