2643102002

Overview

The Fair-Rite Products Corp. part number 2643102002 is a solid, free-hanging ferrite core designed for electromagnetic interference suppression. Constructed from Material 43, this cylindrical component provides an impedance of 235 Ohms at a test frequency of 100 MHz. The physical dimensions include an inner diameter of 12.83 mm (0.505 inches), an outer diameter of 25.91 mm (1.020 inches), and a length of 28.58 mm (1.125 inches). It is classified as a round cable core suitable for bulk packaging.

Feature Summary

• Solid cylindrical construction made from Material 43 for effective high-frequency noise attenuation
• Guaranteed minimum impedance specification controlled for EMI suppression applications
• Free-hanging design allows for easy installation on cables without additional mounting hardware

Applications

• Electromagnetic interference suppression on cables
• High-frequency noise filtering in electronic assemblies
• EMI/EMC compliance enhancement for wiring harnesses

Procurement Notes

Verify the specific ordering suffix to ensure the correct material composition and impedance characteristics match the design requirements. Confirm that the package type aligns with manufacturing handling processes. Check RoHS compliance status if restricted substance regulations apply to the final product assembly. Ensure the inner diameter accommodates the target cable gauge without excessive clearance or tight fit issues.

Selection Notes

Select this component when Material 43 properties are required for the target frequency range. The 235 Ohm impedance at 100 MHz indicates suitability for higher frequency noise suppression compared to lower impedance alternatives. Consider the 12.83 mm inner diameter to ensure compatibility with the cable bundle size. Evaluate the solid core design against split-core options based on assembly constraints and maintenance access needs.

Part Context

This part belongs to the Fair-Rite round cable ferrite core series, specifically utilizing Material 43. It is categorized under filters and cable ferrites. The component is actively manufactured and supported with technical documentation including datasheets and CAD models. It serves as a passive component for managing electromagnetic emissions in electronic systems.

Replacement Considerations

Direct substitutes must share the same Material 43 composition, 235 Ohm impedance at 100 MHz, and identical internal diameter of 12.83 mm. Verify external dimensions and length to ensure spatial compatibility within the enclosure. Cross-reference Fair-Rite part numbers with equivalent specifications from other manufacturers if supply chain diversification is necessary.
