2873002302

Overview

Fair-Rite 2873002302 is a solid ferrite core designed for cable suppression applications. It utilizes Material 73, providing an impedance of 41 Ohms at 25 MHz. The component features a multi-aperture design with an inner diameter of 0.75 mm (0.030 inches) and an overall length of 3.45 mm. Packaged in bulk, this part serves as a compact solution for high-frequency noise attenuation on small-diameter conductors.

Feature Summary

• Solid construction with multi-aperture geometry for secure cable retention
• Material 73 composition optimized for specific frequency range performance
• Compact dimensions suitable for tight spatial constraints

Applications

• High-frequency noise suppression on small cables
• EMI filtering in compact electronic assemblies
• Signal integrity enhancement on data lines

Procurement Notes

Verify the Material 73 designation and impedance characteristics against your specific frequency requirements. Confirm that the 0.75 mm inner diameter accommodates your target cable bundle without excessive force. Ensure the solid core design meets your mechanical retention needs compared to hinged alternatives.

Selection Notes

Select this part when a fixed, non-hinged ferrite solution is required for cables under 0.75 mm. Material 73 offers distinct permeability characteristics compared to standard Mix 43 or 61. Consider the 41 Ohm impedance at 25 MHz as the primary performance metric for your EMI mitigation strategy.

Part Context

This component belongs to Fair-Rite's ferrite toroid and ring category, specifically engineered as a solid core rather than a split or clip-on design. It is part of the broader family of cable ferrites used for electromagnetic interference suppression in various industrial and consumer electronics environments.
