LFB143064-000

Overview

The LFB143064-000 is a solid, free-hanging cylindrical ferrite core manufactured by Laird-Signal Integrity Products. It is designed for low-frequency electromagnetic interference (EMI) suppression on cables. The component features an inner diameter of 6.35 mm and an outer diameter of 14.27 mm. It provides an impedance of 120 Ohms at 5 MHz and operates effectively within a frequency range starting from 1 MHz. The material composition is specified as LF (Lead-Free), ensuring compliance with environmental standards.

Feature Summary

• Solid cylindrical construction for secure cable mounting
• Low-frequency EMI filtering capability
• Lead-free material composition

Applications

• Cable shielding for low-frequency noise reduction
• Electromagnetic interference suppression in wiring harnesses
• Signal integrity enhancement for power lines

Procurement Notes

Verify the specific impedance requirement against application needs, as this component targets low-frequency ranges starting at 1 MHz. Confirm that the physical dimensions, specifically the 6.35 mm inner diameter, accommodate the target cable size. Ensure the lead-free material specification meets project environmental compliance requirements before integration.

Selection Notes

Select this component when low-frequency EMI suppression is required rather than high-frequency RF filtering. The solid design allows for easy installation around existing cables without soldering. Consider the 120 Ohm impedance at 5 MHz to ensure it matches the noise spectrum of the application. Verify compatibility with the cable diameter to ensure a snug fit for effective magnetic coupling.

Part Context

This ferrite core belongs to the family of passive components used for signal integrity and EMI management. Unlike surface-mount beads, this free-hanging type is intended for post-assembly cable treatment. It serves as a simple, effective solution for mitigating conducted emissions in systems where discrete filter components are impractical due to space or configuration constraints.

Replacement Considerations

Direct substitutes must match the 6.35 mm inner diameter and 14.27 mm outer diameter to fit the same cables. Equivalent parts should offer similar impedance characteristics at low frequencies (around 5 MHz). Ensure any replacement also adheres to lead-free material specifications if environmental compliance is mandatory.
