Procurement Notes

Verify the specific part number against official TE Connectivity or Schaffner documentation to confirm electrical parameters such as inductance and current ratings. Ensure the procurement channel provides valid manufacturer traceability. Confirm that the component meets required RoHS compliance standards and matches the specified package dimensions for your PCB layout constraints before finalizing orders.

Selection Notes

Select this component when designing circuits requiring robust common mode noise attenuation for currents up to 1.5 A. The 10 mH inductance value is suitable for standard EMI filtering applications in power lines. Consider the vertical mounting style and 18 mm x 12.5 mm footprint during mechanical layout planning to ensure adequate clearance and thermal management within the target enclosure.

Part Context

This component belongs to the Schaffner RN series of common mode chokes, which are engineered for electromagnetic interference suppression in various electronic systems. The RN series utilizes ferrite cores to provide effective noise filtering while maintaining low insertion loss. These components are widely used in industrial and consumer electronics to meet regulatory emission standards.

Replacement Considerations

Cross-reference with other RN series variants such as RN222-1.5-02-10M if exact matching is required. Verify that substitute parts maintain identical inductance, current ratings, and physical dimensions to ensure compatibility with existing PCB footprints and circuit performance requirements.
