["Description:\n\nFeatures:\nbrand new and high quality\nThis board adopts the principle of the common differential mode lc, which can suppress interference in the switching power supply or other for dc power supply.\nReduce the ripple of the power supply, and reduce the interference brought by the power supply.\nCan be used in low voltage (0 v 50 50 v) for dc power supply circuits, such as power amplifier board, vehicle equipment, industrial control board, for dc electrical appliances, etc.\nThe circuit is flexible to use. When the suppression effect does not meet the requirements, it can be connected in series on several levels to increase the inhibiting capacity. \nWhen the working current of the board does not meet the requirements, it can be connected in parallel with several blocks to increase the output current. \nFor the circuit board using positive and negative power supply, two blocks can be overlapped to form a positive and negative energy interference suppression board. \nThe board can be divided into two voltage specifications, 0 25 25 v, 0 50 50 v. The combined filter plate can be selected according to the working voltage range used.\nThe current of the tpa3116 machine makes the energy input more pure, so the amplifier is less noisy.\nLow voltage for dc (0 v 50 50 v)\n\nTerminal description:\nVin +: positive end of\nVin- input: negative of\nVout + input: positive end of\nVout- output: negative output\n\nSpecification:\nColor: Green+Black\nSize: app. 50x28mm(1.97x1.1in)\nQuantity: 1 pc\n\nNote:\nTransition: 1cm=10mm=0.39inch\nNo retail package.\nPlease allow 1-3cm error due to manual measurement. pls make sure you do not mind before you bid.\nDue to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!\n\nPackage includes:\n1 x Filter Board(other accessories demo in the picture is not included.)"]
