Procurement Notes
Verify the complete part number including suffixes against official KEMET documentation to ensure correct inductance and tolerance specifications. Confirm RoHS compliance status and SVHC declarations prior to procurement. Ensure the selected variant matches the required voltage and current ratings for the specific circuit design.
Selection Notes
Select this component when designing circuits requiring robust common mode noise rejection for high-current AC lines. Consider the physical size constraints for radial leaded components and verify that the operating temperature range meets environmental requirements. Evaluate the DC resistance impact on overall system efficiency.
Part Context
This component belongs to the KEMET SCR31 series of common mode chokes. These filters are engineered for electromagnetic interference suppression in AC power lines. The series offers various inductance values and current ratings to accommodate different power supply designs and noise mitigation needs.
Replacement Considerations
Consult official KEMET substitution guides for verified equivalents. Cross-reference inductance, current rating, and physical dimensions before replacing. Generic substitutes may not match the specific performance characteristics or safety certifications of the original part.
