Procurement Notes
Verify the complete part number against official KEMET documentation to ensure correct series and tolerance specifications. Confirm that the AEC-Q200 certification aligns with specific project requirements. Check for any recent obsolescence notices or alternative package options if leaded versions are restricted by design constraints.
Selection Notes
Select this component when high current capacity and low impedance are critical for noise suppression in automotive power circuits. Ensure the operating temperature range and voltage ratings exceed system peak values. Consider the radial footprint dimensions during PCB layout to accommodate the lead spacing and body size effectively.
Part Context
This component belongs to the SCT series of common mode chokes from KEMET, specifically engineered for demanding automotive environments. The series emphasizes high current performance and durability under thermal stress, distinguishing it from general-purpose industrial filters.
Replacement Considerations
Consult official KEMET substitution guides for verified equivalents. Cross-reference inductance, current rating, and DCR values carefully. Ensure any substitute maintains AEC-Q200 compliance if automotive qualification is required.
