EMI Filter CW1B-1A-L 6A Power Purification Lead Type Single Phase AC Power Filter

1.Product Description

A lead-type single-phase AC power filter is a compact electronic device designed to suppress electromagnetic interference (EMI) and radio-frequency interference (RFI) in single-phase AC power lines. It features integrated leads for easy installation, typically filtering noise in both differential-mode (line-to-line) and common-mode (line-to-ground) to ensure stable power supply and protect sensitive equipment. Commonly used in industrial controls, medical devices, and consumer electronics, it enhances system reliability by reducing harmonics, voltage spikes, and high-frequency noise while complying with EMC standards. Its plug-and-play design simplifies integration into circuits without additional wiring complexity.

1. Electromagnetic Interference Suppression (EMI/RFI Filtering)

Effectively filters out high-frequency noise (conducted interference) in single-phase AC power supplies, including electromagnetic interference (EMI) and radio frequency interference (RFI).

2. Differential-Mode Noise Suppression

Reduces differential-mode interference between power lines (L-N) to prevent voltage fluctuations from affecting equipment.

3. Common-Mode Noise Suppression

Suppresses common-mode noise between power lines and ground (L-G/N-G), enhancing the system's interference resistance.

4. Surge & Spike Protection

Absorbs instantaneous voltage spikes and surges, protecting downstream equipment from damage.

5. Harmonic Reduction

Reduces power supply harmonics, improves power quality, and minimizes interference with the power grid and other equipment.

6. Enhanced System Reliability

Minimizes power supply noise interference with sensitive electronic equipment (such as medical instruments and industrial control systems) to ensure stable operation.

7. EMC Compliance

Meets electromagnetic compatibility (EMC) requirements, such as CISPR, FCC, EN, and other certification standards.

8. Plug-and-Play Design

Features a lead-type design that requires no additional wiring and can be directly connected to the circuit for easy installation.

9. Component Protection

Prevents high-frequency noise from damaging ICs, sensors, communication modules, and other precision components.

10. Extended Equipment Lifespan

Reduces long-term damage to equipment caused by power supply contamination, thereby extending overall service life.

This filter is widely used in industrial automation, medical equipment, communication systems, laboratory instruments, and consumer electronics.
