Product Overview
This 2A DC power supply filter board works on the LC differential common-mode principle — it can suppress interference in switching power supplies or other DC power sources, reduce power supply ripple, and mitigate power-induced interference. It’s suitable for low-voltage DC (0V–50V) power circuits, such as audio amplifiers, in-vehicle devices, industrial control boards, and DC appliances.
- If the suppression effect is insufficient, connect multiple boards in series to enhance interference suppression.
- If the board’s operating current can’t meet demand, connect multiple boards in parallel to increase output current.
- For circuit boards using positive-negative power supplies, stack two boards to form a positive-negative power interference suppression board.
This board comes in two voltage specifications: 0–25V and 0–50V. You can choose a matching filter board based on your operating voltage range.
