ITEM NAME:Assembled 68W+68W HiFi LM3886TF Stereo Amplifier AMP Board 50W*2 / 38W*2 K2M1 Assembled 68W+68W HiFi LM3886TF Stereo Amplifier AMP Board 50W*2 / 38W*2 K2M1 NS LM3886 is the United States launched the mono audio power amplifier chip, using an 11-foot TO-220 package, the back of the "TF" suffix is ??fully insulated package meant. And LM1875T compared to its more powerful, at the rated working voltage up to 68W continuous average power without distortion, also has a relatively perfect over-voltage over-current overheating protection function, in addition it has a current anti switch automatically when shock function. the speaker may be possible to avoid current surge when the amplifier power is turned on causing injury. LM3886 performance parameters at a glance:VCC =+/-28V OUTPUT = 68W / 4ÃŽ ©, 38W / 8ÃŽ ©;VCC =+/-35V OUTPUT = 50W / 8ÃŽ ©;Peak power:135W; SNRLess than or equal to92db;Conversion rate:19V / us;Intermodulation; distortion:0.04%;11 feet TO-220 package. Mute function;SPiKeTM protection;using double-sided alignment, careful layout, signal input portion away from the output section. Ground part of that ground;part of the coupling capacitors for longer minimum pad 5mm, the maximum suitable for the capacitor of 10mm. the input section added high pass circuit, making the board more stable; the output part RL circuit (inductance and resistance in parallel) effective protection chip, effectively preventing the induced electromotive force shutdown speaker damage to the chip! size:106 * 54mm/4.17*2.13 inch chip pitch:51mm/2.01 inch Widening output section traces, and left large electrical flow tin! Germany WIMA coupling enthusiast capacitor decoupling Nikon, Panasonic Silver word negative feedback enthusiast audio capacitors, mute is the day of, Beiru Er capacitance Thomson, the resistance rings are gold film copper foot. LM3886 (original disassemble) is insulated version without the installation of the insulation sheet! Tu-point proposal grease on the line. materi.LM3886 (original disassemble) is insulated version without the installation of the insulation sheet! Tu-point proposal grease on the line.
