HFB159079-100

Overview

The HFB159079-100 is a solid round cylindrical ferrite cable core manufactured by Laird-Signal Integrity Products. It provides electromagnetic interference (EMI) suppression with an impedance of 235 ohms at a test frequency of 300 MHz. The component features an inside diameter of 7.87 mm, an outside diameter of 15.88 mm, and an external length of 28.58 mm. Designed for free-hanging applications, it utilizes high-frequency material to effectively attenuate noise on cables.

Feature Summary

• Solid construction designed for free-hanging installation on cables
• High-frequency material composition for effective EMI suppression
• Cylindrical geometry optimized for round cable cores

Applications

• Electromagnetic interference filtering on signal cables
• Noise suppression on power supply lines
• Data transmission cable protection

Procurement Notes

Verify the specific impedance value of 235 ohms at 300 MHz against your design requirements. Confirm that the 7.87 mm inner diameter accommodates the target cable size. Ensure the solid core type matches the intended free-hanging application rather than split-core alternatives.

Selection Notes

Select this component when a fixed impedance solution is required for round cables. The 7.87 mm bore size dictates the maximum cable diameter. Consider the physical dimensions of 15.88 mm outer diameter and 28.58 mm length for spatial constraints within the assembly.

Part Context

This part belongs to the HFB series of ferrite cable cores from Laird-Signal Integrity Products. These components are engineered for signal integrity applications where discrete EMI filtering is necessary without soldering or complex mounting hardware.

Replacement Considerations

Check datasheets for alternative ferrite cores with matching 235 ohm impedance at 300 MHz. Verify compatibility regarding the 7.87 mm inner diameter and overall physical envelope before substituting.
