• Radial through-hole mounting for secure PCB integration

Applications

• Industrial motor drive systems
• Variable frequency drives (VFDs)
• Power supply input stages
• Electromagnetic interference suppression in heavy machinery

Procurement Notes

Verify the specific suffix codes against official KEMET documentation to ensure exact electrical matching. Confirm that the three-phase topology aligns with your circuit requirements. Check for updated compliance certificates such as RoHS status before finalizing procurement orders.

Selection Notes

Select this component when high current handling capacity above 40 A is required alongside significant inductance values. Ensure the PCB layout accommodates the radial lead spacing and physical dimensions. Consider the thermal management capabilities given the high current rating and operating temperature limits.

Part Context

This part belongs to the KEMET SCF-X series of common mode chokes. These components are engineered specifically for three-phase power applications where robust EMI filtering and high current tolerance are critical. The series offers various inductance and current ratings to suit different industrial power electronics needs.

Replacement Considerations

Direct substitutes include other KEMET SCF-X series parts with similar 50A ratings and 660µH inductance. Verify pin compatibility and physical footprint before swapping. Alternative manufacturers may offer comparable specifications but require thorough validation of insulation and thermal performance.
