Common Mode Chokes Procurement Notes

Verify the specific suffix (e.g., -RC) against official Bourns documentation to confirm packaging type and RoHS compliance status. Ensure the selected variant matches the required inductance tolerance and current rating for the target circuit design before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when a compact SMD solution is required for high-current common mode noise reduction. Compare the 500 µH inductance and 6 A current rating against circuit requirements. Consider the physical footprint and thermal characteristics relative to available board space and operating environment constraints.

Common Mode Chokes Part Context

This part belongs to the PM3700 series of surface-mount common mode chokes from Bourns. The series offers various inductance values and current ratings to suit different EMI filtering needs.
