Description

Capacitor arrangement L20D amplifier power supply board with 68pcs 80V / 220UF caps PLEASE NOTE THE BUYER: There is no wiring diagram, datasheet or instruction manual for this product. Please contact us by email if you need any help, we will try our best to help you, thank you! Parameters: Customized power board kit for L20D amplifier. Size 158 * 69 MM 68 80V220 UF capacitors are used throughout the board. Original 25A bridge stack, double-sided circuit board. Brand new original capacitors (LOW ESR, LONGLIFE, LOW IMPEDANCE, LONG LIFE) Capacitors have a life expectancy of 192,000 hours at 45 degrees Celsius. Capacitors are characterized by an approximate 30% reduction in ESR for a 1x increase in capacity. When two capacitors of the same capacity are connected in parallel, the ESR decreases by 50%. It can be concluded that the use of multiple capacitors in parallel with the same capacity results in lower ESR (equivalent series resistance) and higher filtering performance. Higher filtering performance. And a higher IRAC ripple current can be obtained. The performance is approximately double that of a single capacitor of the same capacity. In other words, the ESR is about twice as low and the current is about twice as high. ESR can be measured with a bridge, and photos are available for reference. This power supply board bulk for 65 yuan, the finished board for 80 yuan. If you need a finished board, please leave a message and change the price. Power supply board + - power supply IRAC :ripple current for + - 12.648A 105C 120 HZ ESR :Equivalent series resistance is 0.0079 ohm. 20 degrees Celsius Lifetime is 10 times longer than normal high capacity AUDIO capacitors (85C 1000 hours). Current is approximately four times that of a typical 63V 10000 UF capacitor. Note: This is an OK board for soldering and testing. We also have bulk models, if you need one, please contact us, thanks! Package: 1pc L20D amplifier spg.supply part board.
