2643480002

Ferrite Cable Overview

The Fair-Rite 2643480002 is a solid, free-hanging ferrite core designed for electromagnetic interference (EMI) and radio frequency interference (RFI) suppression on cables and wiring. Constructed from Fair-Rite Material 43, it operates effectively within the 25 MHz to 300 MHz frequency range. The component exhibits an impedance of 236 ohms at 100 MHz. It features a round cable design with an inside diameter of 4.95 mm, an outside diameter of 12.3 mm, and a length of 25.4 mm. The product complies with RoHS standards.

Ferrite Cable Feature Summary

• Solid construction provides mechanical stability for free-hanging installation on wires
• Material 43 composition ensures high permeability for effective noise attenuation in the VHF/UHF spectrum
• Round geometry accommodates various cable diameters without requiring specialized mounting hardware

Ferrite Cable Applications

• Suppression of EMI/RFI on power and signal cables
• Noise reduction in electronic equipment wiring harnesses
• Filtering high-frequency interference in communication systems

Ferrite Cable Procurement Notes

Verify that the required impedance characteristics align with the specific noise frequencies present in your application. Confirm that the cable diameter falls within the 4.95 mm inner diameter specification to ensure proper fit. Check for RoHS compliance requirements if operating in regulated markets. Ensure the material type matches the intended frequency range of operation.

Ferrite Cable Selection Notes

Select this component when dealing with broadband noise in the 25-300 MHz range. Material 43 is suitable for general-purpose EMI suppression where moderate impedance is sufficient. Consider the physical dimensions to ensure adequate clearance around the cable. Evaluate the thermal environment as ferrite properties can vary with temperature.

Ferrite Cable Part Context

This part belongs to the Fair-Rite 26 series of round cable cores. These components are widely used in the electronics industry for passive filtering solutions. The 2643480002 model specifically utilizes Material 43, which is one of the most common ferrite compositions for suppressing radio frequency noise in consumer and industrial electronics.

Ferrite Cable Replacement Considerations

Direct substitutes must match the 4.95 mm ID, 12.3 mm OD, and 25.4 mm length. Verify that alternative parts offer comparable impedance at 100 MHz and operate within the same 25-300 MHz frequency range. Ensure the replacement also uses Material 43 or an equivalent formulation for similar magnetic performance.
