2643251002

Overview

Fair-Rite 2643251002 is a solid round cable ferrite core made from Material 43. It provides an impedance of 230 ohms at 100 MHz. The component features a cylindrical design with a length of 16.76 mm, an outer diameter of 8.75 mm, and an inner diameter of 4.95 mm. It is classified as a free-hanging type intended for EMI suppression applications.

Feature Summary

• Constructed from Material 43 for high-frequency inductive performance
• Designed as a solid round core for cable insertion
• Provides significant impedance for common-mode choke applications

Applications

• High frequency common-mode chokes
• EMI suppression on cables
• Inductive applications requiring 43-grade material characteristics

Procurement Notes

Verify the inner diameter specification against the target cable or wire bundle dimensions prior to procurement. The 4.95 mm internal clearance is critical for physical fitment. Confirm that the Material 43 composition aligns with the required frequency response for the specific electromagnetic interference environment. Ensure compliance with relevant environmental standards such as RoHS if mandated by the end-use regulations.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable installation. The Material 43 formulation is optimal for suppressing noise in the higher frequency range compared to other grades. Consider the tight inner diameter constraint during mechanical design to ensure the cable can be threaded through without damage. This part is suitable where snap-on cores are not feasible due to space or accessibility limitations.

Part Context

This component belongs to Fair-Rite's round cable ferrite core series, specifically utilizing Material 43. It serves as a passive electromagnetic interference suppression element. The solid construction distinguishes it from split-core alternatives, requiring the cable to be threaded through the center aperture during assembly. It is widely used in electronics manufacturing for signal integrity enhancement.

Replacement Considerations

Check Fair-Rite datasheets for other Material 43 round cores with similar dimensional tolerances. Verify impedance curves at operating frequencies to ensure equivalent noise suppression performance. Confirm that alternative parts maintain the same physical constraints for the existing cable routing path.
