Line Filter

Product Description:

A line filter is an electrical component designed to block unwanted high-frequency noise signals while allowing desired power or data signals to pass through. It is commonly used in both AC and DC circuits to maintain signal integrity and compliance with EMI/RFI regulatory standards.

Key Features:

1. EMI/RFI Suppression: Minimizes interference caused by external or internal sources.
2. Compact Design: Suitable for integration into various electronic systems.
3. Wide Voltage Range: Designed to handle different power input levels.
4. Durability: Made with high-quality materials to ensure long operational life.
5. Compatibility: Can be used in household appliances, industrial equipment, and sensitive electronic devices.

Applications:

• Medical devices
• Industrial machinery
• Communication systems
• Consumer electronics
• Power supplies

Types of Line Filters:

1. Single-Phase Line Filters

   • Designed for use in single-phase electrical systems.
   • Applications: Home appliances, LED drivers, and small industrial devices.

2. Three-Phase Line Filters

   • Suitable for heavy-duty industrial and commercial equipment.
   • Applications: CNC machines, robotics, and HVAC systems.

3. Common Mode Filters

   • Suppress common-mode noise that affects multiple lines simultaneously.
   • Applications: High-frequency digital systems.

4. Differential Mode Filters

   • Target noise between two signal lines.
   • Applications: Audio devices and precision electronics.

Technical Specifications:

1. Voltage Rating:
   • Typically ranges from 120V to 600V, depending on the application.
2. Current Rating:
   • Varies from a few milliamps to hundreds of amps for industrial filters.
3. Insertion Loss:
   • Measured in decibels (dB), indicating how effectively the filter reduces noise.
4. Frequency Range:
   • Designed to filter frequencies between 10 kHz and 30 MHz or more.

Advantages:

• Reduces EMI/RFI for compliance with international standards (e.g., CISPR, FCC).
• Improves the reliability and efficiency of electronic systems.
• Protects sensitive components from damage due to noise.
• Enhances signal clarity in communication and data systems.
