tda2003 power amplifier board single power supply 18V12W mono pure rear stage kit DIY parts
Optimized layout and reduced size, improved on the basis of official circuit, stable and reliable work, professionally designed wiring, no background noise, no humming, real and solid materials! 1.6mm military-grade PCB board, 1% precision resistor, brand new original ST (Fairchild) TDA2003 power amplifier chip, output coupling uses 2200UF high-frequency capacitors, excellent performance, full magnification, larger than TDA2030A power amplifier board, no need to install before It's also easy to get loud volume, with reverse power supply protection, and it won't burn anything if the power supply is reversed.
Power supply voltage: DC 8V-18V (with power supply reverse connection protection!)
Output power: 10W (up to 12W)
Speaker impedance: 1.6Ω-8Ω
Total harmonic distortion: <0.15%
Signal-to-noise ratio: 80dB
Heat generation: DC12V power supply, 1 coin of 1 yuan as heat sink, use TO-220 silicone sheet for heat conduction, computer as audio source, monophonic work, the volume is slightly noisy in a 16 square meter room, continuous work for 4 hours, only touch the coin by hand warm.
Heat sink: The requirements for the heat sink are not high, the metal chassis can be used for heat dissipation, and the thin iron sheet can be used for heat dissipation if the conditions are insufficient!
PCB size: 36*20mm
