2643169552

Overview

Fair-Rite 2643169552 is a solid, free-hanging ferrite core designed for flat ribbon cables. It utilizes Material 43, providing an impedance of 90 ohms at 100 MHz. The component features a split design with internal dimensions of 14.22 mm width by 0.89 mm height and external dimensions of 19.94 mm width by 6.35 mm height. The total length measures 0.400 inches (10.16 mm).

Feature Summary

• Split construction allows installation onto existing flat ribbon cables without disconnecting circuits.
• Material 43 composition provides high impedance characteristics effective for EMI suppression in the frequency range around 100 MHz.
• Solid free-hanging design facilitates easy mounting on cable bundles or individual wires.

Applications

• Suppression of electromagnetic interference on flat ribbon cables in digital systems.
• Noise reduction on data transmission lines within computer peripherals.
• EMI filtering on control signal cables in industrial equipment.

Procurement Notes

Verify the specific impedance requirement matches the application's noise spectrum, as Material 43 performance varies with frequency. Confirm that the internal width accommodates the target flat cable thickness. Check RoHS compliance status if required by project specifications. Ensure the split-core design is suitable for the assembly process compared to snap-on or bead types.

Selection Notes

Select this part when dealing with flat ribbon cables requiring EMI suppression near 100 MHz. Material 43 is appropriate for general-purpose noise reduction where high permeability is needed. Compare internal dimensions against the cable profile to ensure a secure fit. Consider the physical size relative to available space in the enclosure or cable harness layout.

Part Context

This component belongs to Fair-Rite's 2643 series of cable ferrites. The series offers various shapes and materials tailored for different cable types and frequency ranges. Material 43 is a standard choice for broadband noise suppression. The 2643169552 specifically addresses the need for suppressing noise on flat cables using a split-core format.

Replacement Considerations

Direct substitutes include other Fair-Rite split cores using Material 43 with similar internal dimensions, such as those in the CSFF series. Verify impedance curves match the specific noise frequencies. Alternative manufacturers may offer comparable split ferrites, but material composition and dimensional tolerances must be validated for interchangeability.
