2643021801

Overview

Fair-Rite 2643021801 is a solid round ferrite cable core utilizing Material 43 for EMI suppression. It provides an impedance of 131 Ohms at a test frequency of 100 MHz. The component features a free-hanging design with an inner diameter of 1.58 mm, an outer diameter of 5.08 mm, and a length of 11.10 mm.

Feature Summary

• Solid round construction designed for free-hanging installation on cables
• Utilizes Fair-Rite Material 43 for effective high-frequency noise attenuation
• Functions as an electromagnetic interference (EMI) suppression bead

Applications

• Suppression of common-mode noise on electronic cables
• Signal integrity enhancement in data transmission lines
• Electromagnetic compatibility improvement in consumer electronics assemblies

Procurement Notes

Verify the specific Material 43 composition and impedance tolerance against current Fair-Rite datasheets before integration. Confirm that the physical dimensions align with the target cable diameter to ensure proper fitment without mechanical stress. Check RoHS compliance status for regulatory adherence in the destination market.

Selection Notes

Select this part when a solid, non-split core is required for permanent cable assembly. Material 43 is suitable for frequencies ranging from approximately 10 MHz to several hundred MHz. Ensure the cable diameter falls within the 1.58 mm inner diameter specification to allow secure sliding and retention.

Part Context

This component belongs to the Fair-Rite 26 series of shield beads. These are passive magnetic components used to suppress unwanted radio frequency interference. The 2643021801 variant specifically denotes the Material 43 formulation with standard solid geometry, distinct from split-core or multi-aperture designs.

Replacement Considerations

Direct substitutes include other Material 43 solid cores with matching dimensions, such as Fair-Rite 2643021802 if available. Cross-reference impedance curves to ensure equivalent performance at the operating frequency.
