Overview
The LFB143064-100 is a solid free-hanging cylindrical ferrite core manufactured by Laird-Signal Integrity Products. It provides low-frequency electromagnetic interference (EMI) suppression for cables. The component features an inner diameter of 0.250 inches (6.35 mm) and an outer diameter of 0.562 inches (14.27 mm). Its physical length is 0.530 inches (13.46 mm). The impedance rating is 53 ohms at a frequency of 5 MHz.
Feature Summary
- Solid free-hanging design suitable for cable wrapping
- Low-frequency EMI filtering capability
- Cylindrical geometry for uniform magnetic flux distribution
Applications
- Suppression of low-frequency noise on power cables
- Common mode noise reduction in signal lines
- Electromagnetic compatibility enhancement for electronic assemblies
Procurement Notes
Verify the specific impedance requirement matches the application's noise spectrum, as this unit is rated at 53 ohms at 5 MHz. Confirm that the cable diameter fits within the 0.250-inch inner dimension. Check for RoHS compliance status in the latest manufacturer documentation before integration.
Selection Notes
Select this component when low-frequency EMI mitigation is required rather than high-frequency suppression. Ensure the target cable fits securely within the 6.35 mm inner bore. Compare performance against higher impedance variants if the noise frequency exceeds 5 MHz or requires greater attenuation levels.
Part Context
This part belongs to the LFB series of low-frequency EMI cylindrical ferrite cable cores from Laird-Signal Integrity Products. These components are designed to be slipped onto wires or cables to absorb common-mode noise. They differ from surface-mount beads by offering non-destructive installation and reusability on existing harnesses.
Replacement Considerations
The LFB143064-000 is a direct substitute with identical dimensions but a different impedance rating of 120 ohms at 5 MHz. Verify that the increased impedance does not adversely affect the system's electromagnetic compatibility requirements.
