HFB143064-100

Overview

The HFB143064-100 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products, designed for high-frequency electromagnetic interference (EMI) suppression. It features an impedance of 85 Ohms at 300 MHz. The component has an inside diameter of 6.35 mm (0.250 inches), an outside diameter of 14.27 mm (0.562 inches), and a length of 10.00 mm (0.394 inches). This cylindrical core is intended to be slipped over cables to attenuate common-mode noise in the specified frequency range.

Feature Summary

• Solid construction provides durable mechanical support for cable applications
• Optimized for high-frequency EMI attenuation with 85 Ohm impedance at 300 MHz
• Free-hanging design allows easy installation directly onto existing cables

Applications

• High-frequency noise suppression on power and signal cables
• Common-mode choke implementation for data lines
• EMI filtering in electronic equipment harnesses

Procurement Notes

Verify the specific impedance requirement of 85 Ohms at 300 MHz against your application's noise spectrum. Confirm that the 6.35 mm inner diameter accommodates the target cable insulation thickness. Ensure the physical dimensions fit within the available chassis or enclosure space. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a non-wound, solid ferrite solution is preferred for ease of assembly. The 6.35 mm ID suits standard cable sizes requiring moderate current capacity without magnetic saturation concerns typical of wound cores. Consider the 14.27 mm OD for clearance constraints. Compare against the HFB143064-000 if lower impedance (43 Ohms) is sufficient for the target noise frequencies.

Part Context

This part belongs to Laird-Signal Integrity Products' line of cable ferrites, distinct from their surface-mount chip beads like the LI series or CM series common mode chokes. Unlike integrated components, this is a passive core material used as a discrete add-on filter element for wire harnesses rather than PCB-mounted circuits.

Replacement Considerations

The HFB143064-000 is a documented alternative offering 43 Ohms impedance at similar frequencies. Verify if the reduced impedance meets the EMI requirements. No other direct substitutes are confirmed in public documentation.
