This dual DC filter provides substantial reduction of electromagnetic interference on DC power lines in two independent circuits up to 3A each or up to 6A when connected in parallel. Filter provides noise suppression in both directions protecting your DC lines from noise generating by a particular piece of equipment, or protecting your sensitive equipment from noise coming from DC power supply or other loads.
DC filter DCNG5003 offers unrivalled flexibility in configurations - see Applications below. Filter uses plug-in terminal blocks for connections and mounting flanges for easy installation. Its small size makes it easy to fit in many industrial tools. DCNG5003 has many uses - noisy DC supplies, LED lighting, and others.

What is EMI? NIST defines EMI as "“an electromagnetic disturbance that interrupts, obstructs, or otherwise degrades or limits the effective performance of electronics/electrical equipment.” Most conventionally, EMI is understood as undesirable high-frequency signals, and EMI filters as devices that suppress such signals while preserving the "good" ones.
