Laird Technologies Boosts EMI Suppression with Advanced Ferrite Cores

Laird Technologies Boosts EMI Suppression with Advanced Ferrite Cores

2026-08-17

Performance degradation, data transmission errors, and intermittent failures in electronic devices often stem from a pervasive yet invisible threat: electromagnetic interference (EMI). As modern electronics push toward higher performance and more compact designs, effectively suppressing both differential-mode and common-mode EMI has become a critical engineering challenge.

Addressing EMI Challenges With Intelligent Solutions

Electromagnetic interference operates like hidden noise pollution, originating from power lines, data cables, or electronic component radiation. This interference becomes particularly problematic in high-frequency applications. Specialized ferrite cores have emerged as an effective countermeasure, with closed-split designs offering superior magnetic field containment for enhanced EMI suppression.

These innovative components feature a unique split design that allows installation on existing cables without disconnection, significantly simplifying EMI protection implementation. The closed structure provides stronger magnetic field confinement, delivering superior interference suppression compared to traditional solutions.

Two Product Lines for Precision Shielding Across Frequency Bands
28A Series: Comprehensive Protection for Broad Frequency Ranges (30 MHz - 500 MHz)

Engineered for applications requiring wide-frequency EMI suppression, the 28A series demonstrates exceptional performance across the 30 MHz to 500 MHz spectrum. At 100 MHz, these cores provide an impedance value of 210 ohms, effectively absorbing and attenuating both differential and common-mode interference.

Key Specifications:
  • Frequency coverage: Effective across 30 MHz to 500 MHz range
  • Dual-mode suppression: Addresses both differential and common-mode EMI
  • Simplified installation: Split design enables cable mounting without disconnection
  • Cable compatibility: Accommodates cables up to 19.40 mm diameter
  • Compact dimensions: 29.20 mm width × 29.40 mm height with 20.00 mm internal diameter
HFA Series: Specialized High-Frequency Protection (> 500 MHz)

For applications facing high-frequency EMI challenges, the HFA series delivers focused protection above 500 MHz. These cores provide 315 ohms impedance at 500 MHz, precisely shielding high-frequency noise to maintain signal integrity in sensitive applications like high-speed data communication and RF equipment.

Key Specifications:
  • Frequency optimization: Designed specifically for >500 MHz interference
  • High-impedance performance: 315 ohms at 500 MHz for effective high-frequency attenuation
  • Signal protection: Preserves integrity of high-speed data and RF signals
  • Space-efficient design: Compact 29.00 mm × 29.62 mm footprint with 13.00 mm internal diameter
  • Cable compatibility: Supports cables up to 13.06 mm diameter
Technical Advantages of Closed-Split Ferrite Core Solutions

These specialized ferrite cores distinguish themselves through several critical advantages:

Superior EMI suppression: The technology effectively mitigates both differential and common-mode interference, significantly reducing EMI's impact on device performance.

Installation efficiency: The split design allows quick deployment on existing cabling without disconnection, saving time and labor costs—particularly valuable for deployed systems requiring retrofits.

Material quality: High-grade ferrite materials combined with precision manufacturing ensure consistent performance and extended operational lifespan.

Application versatility: Suitable for diverse sectors including consumer electronics, computing, industrial controls, telecommunications, and automotive systems.

As electromagnetic environments grow increasingly complex, effective EMI mitigation has transitioned from optional to essential for reliable device operation. Advanced ferrite core solutions provide engineers with an effective tool to combat interference, ensuring stable performance across various applications and operating conditions.
