Common Mode Chokes Procurement Notes

Verify the specific suffix and packaging configuration against the manufacturer's latest datasheet before ordering. Confirm that the radial lead spacing and body dimensions match the target PCB footprint requirements. Ensure the operating environment does not exceed the specified 120°C thermal limit or 4.3 A current rating to maintain performance integrity.

Common Mode Chokes Selection Notes

Select this component when high current capacity and low insertion loss are required for AC line filtering. The 1.785 mH inductance offers strong attenuation for common mode interference. Consider the through-hole mounting style if mechanical robustness is prioritized over surface area constraints compared to SMD alternatives.

Common Mode Chokes Part Context

This part belongs to KEMET's SC series of common mode chokes, which are engineered for general-purpose EMI filtering. The series typically includes various inductance and current ratings to suit different power levels. The SC-04-E17J specifically targets applications requiring moderate inductance with high current capability in a standard radial form factor.

Common Mode Chokes Replacement Considerations

Check for direct substitutes with identical 1.785 mH inductance and 4.3 A current rating. Verify that any replacement maintains the same 23.5 mm diameter and lead spacing to ensure compatibility with existing assembly processes and PCB layouts without redesign.
