LFB090050-000

Overview

The LFB090050-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It features an inner diameter of 5.00 mm (0.197 inches) and an outer diameter of 9.00 mm (0.354 inches). The component has a length of 7.00 mm (0.276 inches) and provides an impedance of 36 Ohms at 5 MHz. This cylindrical core is designed for suppressing unintended signals on cables or wires.

Feature Summary

• Solid free-hanging construction for easy installation on existing cabling
• Cylindrical geometry with specific inner and outer diameters to accommodate various wire gauges
• Engineered to suppress electromagnetic interference on signal lines

Applications

• Suppressing unintended signals on cables
• Reducing emissions from wires
• General EMI filtering on harnesses

Procurement Notes

Verify the required inner diameter matches the target cable size, as the 5.00 mm ID is fixed. Confirm that the 36 Ohm impedance at 5 MHz aligns with the specific frequency range of the noise being suppressed. Ensure the physical dimensions fit within the available space in the assembly. Check for any specific material requirements regarding temperature or environmental exposure.

Selection Notes

Select this component when a non-split, solid ferrite core is required for permanent or semi-permanent cable treatment. The choice depends on matching the cable diameter to the 5.00 mm inner opening. Consider the impedance profile at the target noise frequency rather than just DC resistance. Evaluate if a split-core variant is needed for retrofitting versus this solid design for new assemblies.

Part Context

This part belongs to the LFB series of round cable cores from Laird-Signal Integrity Products. These components are distinct from surface-mount chip ferrites, serving instead as through-hole or snap-on solutions for wire harnesses. The series focuses on providing broadband attenuation for common-mode noise on external cabling.
