DC Power Filter Board 0-25V/0-50V 2A/3A/4A Class D Power Amplifier Module Interference Suppression Board EMI Suppression

Introduction:
The DC power supply filter board adopts the LC differential common mode working principle, which can suppress the interference in the switching power supply or other DC power supplies, reduce the ripple of the power supply, and reduce the interference caused by the power supply. It can be used in low-voltage DC power circuits, such as power amplifiers. Board cards, vehicle equipment, industrial control boards, DC electrical appliances, etc. This kind of circuit is more flexible to use. When the suppression effect fails to meet the requirements, multiple stages can be connected in series to enhance the suppression capability. When the working current does not meet the requirements, multiple blocks can be connected in parallel to increase the output current. Can be used for circuit boards that use positive and negative power supplies. The two pieces are superimposed to form a positive and negative power interference suppression board. The board is divided into two voltage specifications of 0~25V and 0~50V, and the matching filter board can be selected according to the working voltage range used.
