12V power filter DC2.1 input and output: Applicable to capacitor filtering of 12V audio and video equipment, Applicable to 12V2A DC2.1 adapter input, Both input and output are DC2.1 It contains 3F super capacitor and intelligent buffer system with common mode suppression effect. At the same time, 6 groups of micro-type capacitors are built in for filtering, which is specially used for high-frequency filtering: Including 1uF, 100nF, 10nF, 1nF, 100pF, 10pF. 10% - 100% indication with input voltage indicator. It is equivalent to a large reservoir used for energy storage. After use, the details and dynamic range increase. 10A DC2.1 double male cable is equipped with the machine.
