2643250202

Overview

Fair-Rite 2643250202 is a solid cylindrical ferrite cable core utilizing Material 43 for EMI suppression. It features an impedance of 200 ohms at 100 MHz and an inductance of 2.817 nH. The component has an inner diameter of 3.18 mm, an outer diameter of 6.35 mm, and a length of 25.40 mm. Designed as a free-hanging shield bead, it operates effectively for high-frequency common-mode choke applications.

Feature Summary

• Solid cylindrical construction designed for free-hanging installation on cables
• Material 43 composition optimized for high-frequency noise attenuation
• Provides significant impedance to suppress electromagnetic interference

Applications

• High frequency common-mode chokes
• EMI suppression beads
• Cable shielding applications

Procurement Notes

Verify the specific Material 43 designation and impedance rating against the manufacturer datasheet to ensure compatibility with target frequency ranges. Confirm physical dimensions match the cable bundle requirements. Check RoHS compliance status if required by project specifications. Ensure the solid design suits the intended mounting environment without split-core mechanisms.

Selection Notes

Select this part when a solid, non-split ferrite core is required for permanent cable attachment. Material 43 is suitable for frequencies typically above 10 MHz. Verify that the 3.18 mm inner diameter accommodates the cable insulation thickness. Consider the 200 ohm impedance value relative to the noise spectrum being targeted for effective suppression.

Part Context

This component belongs to Fair-Rite's 26 series of ferrite cable cores. These are distinct from toroidal or snap-on types due to their solid, fixed geometry. The 2643250202 specifically utilizes the standard 43 material formulation, which is widely recognized for general-purpose high-frequency noise reduction in electronic interconnects.
