HFB170070-100

Overview

The HFB170070-100 is a solid free-hanging ferrite cable core manufactured by Laird-Signal Integrity Products. It provides an impedance of 185 Ohms at a test frequency of 300 MHz. The component features a round cylindrical design with an inside diameter of 7.01 mm, an outside diameter of 16.99 mm, and an external length of 20 mm. It is supplied in bulk packaging.

Feature Summary

• Solid construction for durable EMI suppression on cables
• Free-hanging mounting style allows flexible installation
• Round cylindrical geometry fits standard wire bundles

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Noise filtering on round cylindrical cable assemblies
• Signal integrity enhancement in high-frequency data lines

Procurement Notes

Verify the specific impedance value of 185 Ohms at 300 MHz against system requirements. Confirm the internal diameter of 7.01 mm matches the target cable bundle size. Ensure the solid material type aligns with environmental constraints. Check RoHS compliance status through official manufacturer documentation before integration.

Selection Notes

Select this component when a fixed impedance of 185 Ohms is required for broadband noise attenuation. The 7.01 mm inner diameter accommodates specific cable gauges. The solid form factor offers mechanical stability compared to split cores. Verify that the 20 mm length provides sufficient coverage for the noise source location.

Part Context

This part belongs to the HFB series of ferrite cable cores from Laird-Signal Integrity Products. It is designed for general-purpose EMI suppression applications where discrete components are preferred over integrated solutions. The product line focuses on enhancing signal integrity through passive magnetic filtering techniques.

Replacement Considerations

The HFB170070-000 is a related variant within the same series but offers 97 Ohms impedance. Substitution requires verifying if the lower impedance meets the specific noise spectrum requirements. Dimensional compatibility remains similar due to shared family characteristics.
