LFB220140-000

Overview

The LFB220140-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products, designed for EMI suppression on cables. It features an inner diameter of 14.00mm (0.551 inches) and an outer diameter of 22.10mm (0.870 inches). The component has a length of 12.70mm (0.500 inches) and provides an impedance of 28 Ohms at 5MHz. Constructed from LF material, it serves as a passive filter to attenuate high-frequency noise on power and signal lines.

Feature Summary

• Solid construction with free-hanging design for easy cable installation
• Provides effective EMI attenuation in the MHz frequency range
• Compatible with cables up to 14mm inner diameter

Applications

• Suppression of electromagnetic interference on power cables
• Noise filtering for signal transmission lines
• Cable assembly EMI mitigation in electronic equipment

Procurement Notes

Verify the specific material grade and impedance tolerance against current datasheets before integration. Confirm that the 14mm inner diameter accommodates the target cable bundle size without excessive strain. Ensure the operating environment does not exceed the thermal limits of the LF material composition specified by the manufacturer.

Selection Notes

Select this component when a non-adhesive, slide-on ferrite solution is required for cables exceeding standard snap-on core dimensions. The 28 Ohm impedance at 5MHz targets specific low-to-mid frequency noise profiles. Consider the physical bulk of the 22.10mm outer diameter for spatial constraints within the final enclosure or cable routing path.

Part Context

This part belongs to the family of free-hanging ferrite cores used for post-assembly cable treatment. Unlike surface-mount beads, these are installed manually or via automated insertion onto finished cables. They are distinct from clip-on or adhesive cores due to their open-loop geometry, allowing them to be slipped over existing connectors or wire harnesses during manufacturing or maintenance.

Replacement Considerations

Direct substitutes must match the 14mm inner diameter and 28 Ohm @ 5MHz impedance characteristics. Verify that alternative solid cores maintain similar physical dimensions to ensure fitment within the designated cable management area.
