Power Line Filter

How to Choose the Right Power Line Filter for Shielded Room Applications

1. Why Proper Selection Matters

Selecting the wrong power line filter for a shielded room can result in:

  • Insufficient attenuation

  • Increased leakage

  • EMC compliance failure

  • Costly redesigns

A shielded facility requires a filter specifically designed for structural integration and high-performance EMI suppression.


2. Key Selection Factors

✔ Rated Voltage and Current

Determine whether your system requires:

  • Single-phase

  • Three-phase

  • High-current industrial configuration

✔ Frequency Attenuation Requirements

Check insertion loss curves across relevant ranges (150 kHz – 30 MHz and beyond if required).

✔ Structural Integration

Ensure compatibility with:

  • Shield wall mounting thickness

  • Bolt pattern

  • Ground bonding interface

✔ Certification Requirements

Depending on application, CE, MIL, or other documentation may be required.


3. Why Work with an EMC-Focused Manufacturer

Shielded room filters are not generic industrial components. They must be engineered specifically for shielding facilities.

Noordin Etech provides power line filters designed for shield-class facilities, offering:

  • High insertion loss performance

  • Stable mechanical construction

  • Support for custom voltage and current configurations

  • Engineering assistance for integration
