2643800502

Overview

Fair-Rite 2643800502 is a solid, round cable ferrite core utilizing Material 43 for EMI suppression. It features an inner diameter of 13.21 mm (0.520 inches), an outer diameter of 20.96 mm (0.825 inches), and a length of 11.89 mm (0.468 inches). The component provides an impedance of 82 ohms at 100 MHz. Designed for free-hanging installation, it operates within a temperature range of -55°C to +90°C.

Feature Summary

• Solid construction made from Fair-Rite Material 43 for effective high-frequency noise attenuation
• Round geometry designed for sliding onto cables without requiring assembly hardware
• Free-hanging mounting style allows for flexible placement on wires and harnesses

Applications

• EMI suppression on power and signal cables
• Noise filtering in electronic equipment wiring
• Common mode choke applications for cable assemblies

Procurement Notes

Verify the specific Material 43 designation and impedance characteristics against the official Fair-Rite datasheet before integration. Confirm that the physical dimensions match the cable bundle size to ensure proper fit. Check RoHS compliance status as required by your manufacturing standards. Ensure the operating temperature range meets the environmental conditions of the final application.

Selection Notes

Select this component when a large aperture is required for thick cables or multi-conductor bundles. Material 43 is suitable for frequencies typically between 1 MHz and 100 MHz. Compare the 82-ohm impedance requirement against other materials if higher frequency performance is needed. Ensure the solid design accommodates the cable insulation thickness without excessive stress.

Part Context

This part belongs to Fair-Rite's line of round cable EMI suppression cores. Material 43 is a manganese-zinc ferrite known for its high permeability and moderate resistivity, making it ideal for suppressing electromagnetic interference in the lower radio frequency spectrum. These cores are widely used in industrial and commercial electronics for cable protection.
