LFB159079-000

Overview

The LFB159079-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It features an inner diameter of 7.87mm (0.310 inches) and an outer diameter of 15.88mm (0.625 inches). The component has a length of 28.58mm (1.125 inches) and provides an impedance of 100 Ohms at 5 MHz.

Feature Summary

• Solid cylindrical ferrite construction for cable wrapping
• Free-hanging mounting style suitable for wire harnesses
• High impedance performance at 5 MHz for EMI suppression

Applications

• Cable assembly noise filtering
• Power supply line EMI suppression
• Signal cable interference reduction

Procurement Notes

Verify the specific impedance requirement of 100 Ohms at 5 MHz against design specifications. Confirm that the 7.87mm inner diameter accommodates the target cable bundle size. Ensure the free-hanging form factor fits within the available enclosure space without mechanical interference.

Selection Notes

Select this component when a non-split, solid ferrite core is required for permanent cable installation. The 100 Ohm impedance at 5 MHz targets lower frequency noise compared to higher-frequency chip beads. Consider the physical dimensions for routing constraints in tight assemblies.

Part Context

This part belongs to the family of solid ferrite cores used for electromagnetic interference suppression on cables. Unlike split cores, it requires the cable end to be threaded through during assembly. It serves as a passive component to attenuate common-mode noise on power and signal lines.

Replacement Considerations

Direct substitutes must match the 7.87mm inner diameter and 100 Ohm @ 5 MHz impedance. Verify that alternative solid cores maintain similar material properties for equivalent attenuation characteristics at the target frequency.
