2508051218Y0

Overview

The Fair-Rite 2508051218Y0 is a ferrite core assembly designed for electromagnetic interference suppression. It features a split-core construction with a snap-fit mechanism, allowing installation around existing cables without disconnection. The material composition utilizes a high-permeability ferrite formulation optimized for noise absorption in the MHz frequency range. This component serves as a passive filter element to attenuate common-mode currents on signal and power lines.

Feature Summary

• Split-core design enables rapid retrofitting onto pre-existing wiring harnesses
• Snap-fit closure ensures secure mechanical retention during vibration
• Ferrite material provides high impedance to high-frequency noise

Applications

• Attenuating EMI on internal computer bus cables
• Noise suppression on automotive sensor wiring
• Filtering conducted emissions on industrial control panel cabling

Procurement Notes

Verify the specific material number (18) matches the target frequency spectrum of the application. Confirm the inner diameter accommodates the cable bundle diameter including insulation. Ensure the snap-fit latch integrity is intact upon receipt. Cross-reference the manufacturer's datasheet for temperature ratings relevant to the operating environment.

Selection Notes

Select based on the required impedance profile at the specific noise frequencies present. Evaluate the physical constraints of the installation space to ensure the split-core geometry fits. Consider the thermal stability of the ferrite material relative to the ambient operating conditions. Verify compatibility with the cable outer diameter to maintain effective magnetic coupling.

Part Context

This part belongs to the Fair-Rite snap-on ferrite bead series. These components are engineered for easy integration into electronic assemblies where post-assembly noise filtering is required. The numbering system indicates the core shape, material type, and specific dimensional tolerances defined by the manufacturer.

Replacement Considerations

Substitute parts must match the original material permeability and inner diameter. Verify that alternative snap-fit mechanisms provide equivalent mechanical retention. Ensure the replacement component meets the same impedance specifications at the critical frequencies.
