Component Specifications

Definition
A specialized shielding and casing component designed to protect delay line elements from electromagnetic interference (EMI), radio frequency interference (RFI), and physical damage. It maintains signal integrity by preventing external noise from distorting timing signals while providing mechanical protection and thermal management for sensitive delay circuitry.
Working Principle
Operates on Faraday cage principles to block external electromagnetic fields through conductive materials, while providing physical protection and thermal dissipation. The shielding creates an isolated environment that prevents signal degradation in delay lines by reflecting/absorbing interfering electromagnetic waves.
Materials
Typically aluminum alloys (6061, 5052), copper alloys (C11000), or steel with conductive coatings. May include nickel-plated steel for enhanced shielding effectiveness. Internal linings often use conductive elastomers or EMI gaskets for complete enclosure sealing.
Technical Parameters
  • VSWR <1.5:1
  • Dimensions Custom to delay line specifications
  • Insertion Loss <0.5 dB
  • Surface Finish Conductive coating with ≤0.5μm roughness
  • Operating Temperature -40°C to +85°C
  • Shielding Effectiveness 40-80 dB @ 1-10 GHz
Standards
ISO 11452-2, IEC 61000-4-3, MIL-STD-461, DIN EN 55032

Frequently Asked Questions

Why is shielding important for delay lines?

Delay lines are sensitive to electromagnetic interference which can distort timing signals. Shielding prevents external noise from affecting signal propagation time and amplitude.

What materials provide best EMI shielding for delay lines?

Copper offers superior conductivity (best for magnetic fields), aluminum provides good general shielding with lighter weight, while steel with conductive coatings offers robust physical protection.

How does casing design affect delay line performance?

Proper casing design minimizes parasitic capacitance, provides adequate thermal dissipation, and ensures complete electromagnetic sealing without creating resonance cavities that could affect signal quality.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
