Three groups of -capacitors filter the spike ripple. 3 groups of -capacitor filtering, each group of 2 0.001uF, 0.01uF, 0.1uF for the last high-frequency ripple filter 6 groups of 47uF low ESR tantalum polymer capacitors connected in parallel 2CH common-mode suppression filter circuits effectively suppress the power ripple from your power adapter With IR receiver Support type C and DC2.1 input 5V Power supply filter capacitor capacity 6F=6000000F Professional power filter board for After input power supply is filtered by 2 sets of common-mode suppression filter circuits, the secondary power supply is reformed by 6 super capacitors EDLC, and then filtered by 6 low ESR tantalum polymer capacitors, and finally sent to 3 groups of microcapacitors to complete purification All GPIO pin headers are led out for easy expansion Super capacitor power filter for For moode, volumio, picoreplayer, runeaudio After installation, the sound quality and hearing experience become better, and the power is surging The super capacitor board is 2 levels of common mode rejection 6 super capacitors 6 low internal resistance 47uf tantalum polymer capacitors in parallel 3 sets of microcapacitor filter output to Pi With infrared receiver for remote control After fully , the instantaneous discharge current over 10A Colour:White Material:PC+metal Package Contents: 1 x Super Capacitor Filter Board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
