High Quality AC Line EMI Filters

AC Line EMI Filter for Reliable Noise Suppression in Power Systems

FERRTX AC Line EMI Filter solutions are designed to eliminate conducted noise and interference on AC mains input, providing stable and compliant operation across demanding industrial, commercial, and consumer power systems. As a key member of our emi rfi ac power line filters portfolio, this product offers robust attenuation for both differential-mode (DM) and common-mode (CM) noise.

Compared with conventional EMI Filters, this enhanced model adopts optimized magnetic design and improved capacitor layout to ensure low leakage current, high reliability, and reduced temperature rise. The result is cleaner AC input and improved electromagnetic compatibility for switching power supplies, chargers, control systems, and energy-storage equipment.

Optimized Design for Clean AC Mains Power

High Attenuation Performance

Through advanced core selection and internal winding geometry, the filter delivers strong noise suppression across a wide frequency spectrum—ideal for both industrial and household EMC requirements.

The use of a high-performance Power Line Common Mode Choke significantly strengthens CM attenuation while maintaining low insertion loss.

Thermally Stable & Safe Operation

Heat-optimized internal structure, flame-retardant materials, and carefully selected capacitors ensure long-term reliability even under continuous high-current operation.

Compact Structure for Easy Integration

The compact enclosure allows drop-in installation for SMPS, EV chargers, industrial control panels, and other AC input sections.

Typical Applications

Our AC Line EMI Filter is widely used in:

• AC-DC power supplies for telecom, networking, and servers

• EV charging stations & industrial battery systems

• Automation controllers and programmable logic systems

• Medical devices requiring low leakage EMI control

• Consumer appliances and smart-home power modules

• Power entry modules with integrated filtering

The product is fully compatible with high-frequency SMPS front-end designs and Transformer-isolated power architectures, including systems using Transformer or High Frequency Transformer stages.

Key Features

• High CM/DM noise attenuation for AC mains environments

• Low leakage current meeting global safety standards
