2512061216Y0A4

Overview

The Fair-Rite 2512061216Y0A4 is a ferrite bead assembly designed for electromagnetic interference suppression in high-frequency circuits. It features a split-core snap-on configuration, allowing installation on existing cables without disconnection. The component utilizes a specific ferrite material formulation optimized for attenuation characteristics within defined frequency ranges. Key electrical parameters include impedance values measured at standard frequencies, typically specified in ohms, which determine its effectiveness in filtering noise. The physical dimensions are standardized to fit common cable diameters, ensuring secure mechanical retention while maintaining consistent magnetic coupling for effective signal integrity preservation.

Feature Summary

• Snap-on design enables non-intrusive installation on pre-existing wiring harnesses
• Ferrite material composition provides targeted high-frequency noise attenuation
• Split-core construction allows access to cables in confined or assembled spaces

Applications

• Suppression of common-mode noise on data communication cables
• EMI reduction in automotive electronic control unit wiring
• Filtering noise on power supply lines in industrial equipment

Procurement Notes

Verify the specific ferrite material number and impedance specifications against the official Fair-Rite datasheet for the exact part code. Confirm that the inner diameter matches the target cable outer diameter to ensure proper fit and magnetic performance. Check for any RoHS compliance documentation if required by your manufacturing standards. Ensure the ordering suffix corresponds to the correct packaging or variant if applicable.

Selection Notes

Select this component based on the required impedance profile at the target noise frequencies rather than general size alone. Evaluate the cable diameter to ensure the split-core opening accommodates the wire bundle securely. Consider the ambient temperature range and current carrying capacity of the cable, as the ferrite core may influence thermal dissipation. Compare alternative materials if higher attenuation is needed at different frequency bands.

Part Context

This part belongs to Fair-Rite's line of snap-on ferrite beads, which are distinct from through-hole or surface-mount components. These assemblies are commonly used in post-assembly EMI mitigation where space constraints prevent the use of larger chokes. The numbering system indicates the material type, case size, and specific impedance characteristics defined by the manufacturer's internal classification.

Replacement Considerations

Substitute parts must match the original impedance curve and inner diameter precisely. Verify that any alternative snap-on bead offers equivalent attenuation at the critical noise frequencies. Ensure the replacement maintains the same mechanical retention force to prevent vibration-induced loosening.
