Procurement Notes

Verify the specific voltage and current ratings against your system requirements before procurement. Confirm that the operating temperature range aligns with your environmental conditions. Ensure the physical dimensions fit within your designated chassis or PCB space. Check for any recent product change notices regarding material or manufacturing updates.

Selection Notes

Select this component when high current capacity and stable common mode noise suppression are required. The compensated nature makes it suitable for applications where inductance stability is critical. Consider the toroidal form factor for its compact footprint and low electromagnetic emission profile compared to other core types.

Part Context

This part belongs to the RD series of compensated chokes from Schaffner. These components are engineered for high-performance EMC filtering in power electronics. The series is known for combining high saturation current with precise inductance control, making it a standard choice for rigorous industrial and medical standards compliance.

Replacement Considerations

Direct substitutes must match the 2.8 mH inductance, 16 A current rating, and toroidal package dimensions. Verify that alternative components offer comparable compensation characteristics and voltage ratings to ensure equivalent circuit performance.
