Procurement Notes

Verify the specific suffix code against official TDK documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with surface mount reflow soldering profiles. Confirm that the selected variant meets the required AEC-Q200 qualification level for your specific automotive application environment.

Selection Notes

Select this component when high current capacity and automotive reliability are prioritized over minimal footprint. The horizontal package requires adequate clearance on the PCB layout. Consider the 8.8 mΩ DC resistance impact on voltage drop if efficiency is critical. Verify thermal management requirements given the 10.4 A rating and operating temperature limits.

Part Context

This part belongs to the B82722S family of surface mount common mode chokes designed by EPCOS (TDK). The series targets automotive and industrial applications where space constraints and high current handling are necessary. It complements through-hole alternatives like the B82726 series by offering a lower profile solution for modern PCB designs.

Replacement Considerations

Direct substitutes must match the 630 µH inductance, 10.4 A current rating, and 30.99 mm x 25.40 mm footprint. Verify AEC-Q200 certification if used in automotive contexts. Cross-reference pinout and mounting orientation to ensure mechanical compatibility without redesigning the PCB.
