2631480002

Overview

Fair-Rite 2631480002 is a round cable ferrite core designed for EMI suppression. It utilizes Fair-Rite Material 31, optimized for the 1 MHz to 300 MHz frequency range. The component provides a minimum impedance of 295 ohms at 100 MHz. Physical dimensions include an outer diameter of 0.485 inches and an inner diameter of 0.200 inches.

Feature Summary

• Solid round cable core construction for permanent installation on wires
• Material 31 composition engineered for high-frequency noise attenuation
• Guaranteed minimum impedance specification ensures consistent filtering performance

Applications

• Electromagnetic interference suppression on signal cables
• Common mode noise reduction in electronic assemblies
• High-frequency circuit protection components

Procurement Notes

Verify material composition and impedance specifications against current Fair-Rite datasheets prior to procurement. Confirm physical dimensions match cable requirements. Check RoHS compliance status as manufacturing processes may evolve. Ensure ordering suffixes are correctly interpreted regarding packaging or testing variations.

Selection Notes

Select this component when operating frequencies fall within the 1 MHz to 300 MHz range. Material 31 offers specific permeability characteristics suitable for these applications. Verify that the 0.200-inch inner diameter accommodates the target cable bundle without excessive force. Consider the 295-ohm impedance requirement for effective noise suppression in the design.

Part Context

This part belongs to the Fair-Rite round cable EMI suppression core series. These solid cores differ from split or toroidal designs by requiring cable insertion during assembly. Material 31 is distinct from other Fair-Rite formulations like 43 or 61, offering tailored performance for specific frequency bands.

Replacement Considerations

Direct substitutes must match Material 31 composition and similar impedance curves. Alternative Fair-Rite part numbers with identical inner and outer diameters may serve as replacements if impedance values meet or exceed the original specification.
