2873002402

Overview

Fair-Rite 2873002402 is a solid cylindrical ferrite core utilizing Material 73. It features an outer diameter of 7 mm, an inner diameter of 1.7 mm, and a length of 6.2 mm. The component provides an impedance of 77 Ohms at 25 MHz. Designed for suppression applications, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Solid cylindrical geometry designed for direct installation on round cables
• Material 73 composition optimized for high-frequency noise suppression
• Multi-aperture structural design suitable for balun and broadband transformer construction

Applications

• Electromagnetic interference (EMI) suppression on round cables
• Construction of balance-unbalance (balun) transformers
• Broadband transformer implementation in RF circuits

Procurement Notes

Verify the specific material grade and dimensional tolerances against the official Fair-Rite datasheet before integration. Confirm that the solid cylindrical form factor aligns with the cable diameter requirements of the target assembly. Ensure compliance with RoHS3 specifications as documented in the manufacturer's environmental declarations.

Selection Notes

Select this component when high-frequency attenuation is required directly on the cable rather than through a separate housing. Material 73 offers superior performance in the VHF/UHF spectrum compared to standard mixtures. The solid design simplifies assembly by eliminating the need for split-core clamping mechanisms.

Part Context

This part belongs to the Fair-Rite multi-aperture core family, which includes variants like 2843002402 and 2873002302. While other models may feature hollow or oval geometries, the 2873002402 utilizes a solid cylinder configuration specifically engineered for direct cable mounting and compact suppression tasks.

Replacement Considerations

Direct substitutes include Fair-Rite 2843002402 for similar material properties but different geometry. For identical dimensions with different frequency characteristics, evaluate cores using Material 43. Verify cross-compatibility based on specific impedance curves and physical clearance constraints.
