Jack DC Supercapacitor Filter 9V

This DC 9V jack filter with supercapacitor allows you to obtain a clean power supply for your Hi-Fi equipment and appliances, thanks to 4 supercapacitors 5F - 3.0V and an intelligent buffer system with common mode suppression effect. It also incorporates a UTC UZ1085L linear voltage regulator, an STC 8H1K08 microcontroller and a ME85P03 MOSFET transistor. Input and output are on DC 5.5/2.1mm jack connectors. LEDs indicate the Jack DC filter loading: 10%, 25%, 50%, 75%, 100%. It is itself powered by 9V 3A via its DC jack input.
