461178181

Overview

The Fair-Rite Products Corp. model 461178181 is a split core ferrite assembly designed for electromagnetic interference suppression on round cables or bundled wires. It features an internal diameter of 4.1 mm and operates within a frequency range starting at 200 MHz. The component provides an impedance of 215 ohms, ensuring controlled attenuation characteristics for signal integrity management in electronic systems.

Feature Summary

• Split core design allows installation around existing cables without disconnection
• Controlled impedance performance for effective high-frequency noise suppression
• Accommodates round cables and bundled wire configurations

Applications

• Electromagnetic interference suppression on wiring harnesses
• Signal integrity management for bundled cables
• High-frequency noise attenuation in electronic assemblies

Procurement Notes

Verify the specific impedance value and frequency range against the official Fair-Rite datasheet before integration. Confirm that the 4.1 mm internal diameter matches the target cable bundle dimensions to ensure proper fit and magnetic coupling efficiency.

Selection Notes

Select this component when retrofitting EMI suppression onto existing cabling is required due to its snap-open construction. Ensure the application involves round cables or bundles fitting within the 4.1 mm aperture and requires attenuation characteristics aligned with the specified 215 ohm impedance profile.

Part Context

This part belongs to the Round Cable Snap-It™ family from Fair-Rite, which offers pre-assembled ferrite solutions for various suppression materials. These kits are engineered to provide consistent impedance control across different frequency bands, simplifying the selection process for standard cable sizes compared to loose cores.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative Fair-Rite Snap-It™ assemblies based on material composition and impedance curves.
