Bảng Mạch Khuếch Đại Âm Thanh BTL TPA3221 Cho Loa

Description: The use of high-quality parts not only guarantees safety and quality, and has a long service life, but more importantly, it is a strong guarantee that the actual performance can reach the design goal. Using TPA3221 The main filter electrolytic capacitor adopts the imported famous brand Erkang with a capacity of 2200UF/35V*4, which ensures strong and continuous power support. The resistors are high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine. The use of special magnetic ring inductors for audio ensures that the sound is clear and powerful. 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. Specification: Working voltage: DC19V-30V switching power supply (DC) DC24V is recommended Size:4.06x3.07 inch Package Includes: 1 x Amplifier board
