Procurement Notes
Verify the specific part number against official TE Connectivity or Schaffner documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with existing PCB layouts regarding through-hole spacing and mounting orientation. Cross-reference datasheets for thermal performance limits under actual operating conditions.
Selection Notes
Select this component based on the required 12 A current handling and 5 mH inductance specifications. Consider the horizontal mounting style for space-constrained PCB designs. Verify that the unshielded nature meets the system's electromagnetic compatibility requirements without additional shielding measures.
Part Context
This component belongs to the RT-Series of common mode chokes from Schaffner EMC Inc., now part of TE Connectivity. The series offers various configurations including 2-wire and 3-wire options with different current and inductance ratings. These filters are engineered for robust electromagnetic compatibility in demanding industrial environments.
Replacement Considerations
Consult official manufacturer substitution lists for verified equivalents. Generic alternatives may not match the specific current compensation characteristics or dimensional constraints of the original design.
