2643025601

Overview

Fair-Rite 2643025601 is a cylindrical solid ferrite core designed for EMI suppression. It utilizes Material 43, providing an impedance of 55 ohms at 100 MHz. The component features a 1.6 mm inner diameter and a 3.5 mm outer diameter. Its physical length is 6 mm. This shield bead is intended for free-hanging installation on cables to attenuate high-frequency noise.

Feature Summary

• Solid cylindrical construction for direct cable mounting
• Material 43 composition optimized for high-frequency noise absorption
• Designed as a shield bead for effective EMI suppression

Applications

• Suppression of electromagnetic interference on signal cables
• Noise filtering in electronic equipment wiring
• Shield bead application for cable harnesses

Procurement Notes

Verify the specific impedance value of 55 ohms at 100 MHz against your design requirements. Confirm that the 1.6 mm inner diameter accommodates the target cable gauge. Ensure Material 43 characteristics align with the intended frequency range for effective attenuation performance.

Selection Notes

Select this part when a compact, solid ferrite bead is required for low-profile cable applications. The 1.6 mm bore size limits usage to smaller gauge wires. Material 43 selection depends on the specific frequency spectrum of the noise to be suppressed, offering high permeability for effective damping.

Part Context

This component belongs to the Fair-Rite 26 series of ferrite cable cores. It is categorized under EMI suppression beads within the broader ferrite materials family. The product serves as a passive filter element, distinct from split-core or toroidal designs, offering a fixed geometry for permanent installation.

Replacement Considerations

Check for equivalent parts with matching 1.6 mm ID and 55 ohm impedance at 100 MHz. Verify Material 43 compatibility to ensure similar magnetic properties. Dimensions must align for mechanical fit in existing assemblies.
