HFB143064-200

Overview

The HFB143064-200 is a hinged ferrite core manufactured by Laird-Signal Integrity Products, designed for high-frequency EMI suppression on cables. It features an inner diameter of 0.250 inches (6.35 mm) and an outer diameter of 0.562 inches (14.27 mm). The component provides an impedance of 158 Ohms at 300 MHz. Its physical length allows for secure clamping around wires to mitigate electromagnetic interference in signal and power lines.

Feature Summary

• Snap-on hinged design enables rapid installation and removal without disconnecting cables
• High-frequency noise attenuation capability optimized for EMI filtering applications
• Cylindrical geometry accommodates standard cable diameters within specified bore limits

Applications

• Suppression of electromagnetic interference on data communication cables
• Noise reduction on power supply lines in electronic equipment
• EMI mitigation in industrial control wiring harnesses

Procurement Notes

Verify the specific impedance requirement of 158 Ohms at 300 MHz against your system's noise spectrum before procurement. Confirm that the cable diameter falls within the 0.250-inch inner diameter tolerance to ensure proper mechanical fit and magnetic coupling. Check for RoHS compliance status if your assembly requires restricted substance-free components, as this specific part may have varying environmental declarations depending on the manufacturing batch.

Selection Notes

Select this component when a non-invasive, reusable ferrite solution is required for existing cable assemblies. The hinged mechanism distinguishes it from slide-on cores, offering convenience for maintenance or prototyping phases. Ensure the selected core material supports the target frequency range of interest, specifically verifying performance near 300 MHz for effective attenuation.

Part Context

This part belongs to the HFB series of high-frequency cylindrical ferrite cable cores produced by Laird-Signal Integrity Products. These components are engineered to provide broadband noise suppression for various wire types. The series offers multiple impedance values and dimensions to suit different cable sizes and frequency requirements.

Replacement Considerations

Direct substitutes include other hinged ferrite cores with matching 158 Ohm impedance at 300 MHz and compatible inner/outer diameters. Verify mechanical compatibility with the existing cable bundle before swapping manufacturers.
