Procurement Notes
Verify the manufacturer designation as TE Connectivity / Schaffner when sourcing. Confirm RoHS compliance status through official datasheets or distributor declarations. Ensure the specific 7.5 mH inductance rating matches the circuit requirements. Check for any obsolete status or lifecycle changes directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component for applications requiring three-line common mode filtering with a 6 A current rating. The 7.5 mH inductance at 400 Hz suits standard power line frequencies. Consider the through-hole package and physical dimensions for PCB layout constraints. Verify thermal management capabilities given the operating temperature limits and current handling specifications.
Part Context
This part belongs to the RD series of common mode chokes from Schaffner EMC Inc., now under TE Connectivity. The series focuses on providing effective electromagnetic interference suppression for various electronic systems. These components are designed to meet stringent EMC standards while maintaining compact form factors suitable for diverse industrial and commercial applications.
Replacement Considerations
Consult official TE Connectivity / Schaffner documentation for verified substitute part numbers. Cross-reference inductance values, current ratings, and physical dimensions to ensure compatibility. Do not assume interchangeability without validating electrical parameters against the original specification sheet.
