Procurement Notes
Verify the specific suffix and package dimensions against the official Bourns datasheet to ensure compatibility with your PCB footprint. Confirm that the 6 A current rating meets your circuit requirements under expected operating temperatures. Check for AEC-Q200 compliance if automotive application is required.
Selection Notes
Select this component when high current capacity is critical alongside common mode noise reduction. The low DCR minimizes power loss compared to higher resistance alternatives. Ensure the 12.5 µH inductance aligns with your target frequency attenuation needs.
Part Context
This part belongs to the SRF1206A series of shielded common mode chokes from Bourns. The series is engineered for compact designs requiring robust performance in automotive and industrial environments. It utilizes ferrite core technology for effective EMI suppression.
Replacement Considerations
Check for direct substitutes within the SRF1206A series or other Bourns CMC lines with matching 12.5 µH inductance and 6 A current ratings. Verify pinout and mechanical dimensions before substitution.
