2643800302

Overview

Fair-Rite 2643800302 is a solid round cable ferrite core utilizing 43 Material. It features an inner diameter of 7.16 mm, an outer diameter of 12.70 mm, and a length of 4.78 mm. The component provides an impedance of 42 ohms at 100 MHz. Designed for EMI suppression, it operates effectively within the frequency range of 25 MHz to 300 MHz. The part complies with RoHS standards.

Feature Summary

• Solid construction designed for free-hanging installation on cables
• Utilizes Fair-Rite 43 Material for high permeability in the VHF/UHF spectrum
• Provides effective electromagnetic interference suppression

Applications

• EMI suppression on data cables
• Noise reduction on power supply lines
• Signal integrity enhancement in communication equipment

Procurement Notes

Verify the specific material grade (43) and impedance value (42 ohms @ 100 MHz) against your design requirements. Confirm physical dimensions match the target cable diameter. Ensure RoHS compliance meets regulatory needs. Check datasheet for temperature stability characteristics relevant to your operating environment.

Selection Notes

Select this component when targeting noise suppression in the 25-300 MHz range. The 43 material offers optimal performance for digital signal harmonics. Ensure the 7.16 mm inner diameter accommodates the cable bundle. Consider the solid form factor for easy snap-on installation without splitting the core.

Part Context

This part belongs to Fair-Rite's line of round cable cores. It is distinct from split cores or toroidal rings. The 43 material composition differentiates it from other grades like 31 or 61, which are optimized for different frequency ranges. This specific model is a standard off-the-shelf component for general-purpose EMI filtering.
