• Power conditioning units requiring common-mode noise reduction

Procurement Notes

Verify the specific pin configuration and mechanical footprint against your PCB layout before ordering. Confirm that the operating temperature range meets your environmental requirements. Ensure the current rating aligns with your system's peak load demands. Check for any specific packaging preferences as distribution may vary. Always refer to the latest manufacturer datasheet for final dimensional and electrical validation.

Selection Notes

Select this component when high current capacity and low impedance are critical for AC line filtering. Consider the through-hole mounting requirement and available board space for its horizontal profile. Evaluate the thermal performance to ensure it remains within safe operating limits under continuous load. Compare inductance values against other series if stricter noise attenuation is required.

Part Context

This part belongs to KEMET's SC series of common-mode chokes, which are engineered for power line applications. The series is known for providing reliable EMI suppression in demanding environments. These components are widely used in industrial and commercial electronics where stable operation and noise immunity are essential for system integrity.

Replacement Considerations

Check for compatible parts within the same SC series or equivalent models from other manufacturers offering similar inductance and current ratings. Verify that substitute components match the physical dimensions and pinout to ensure compatibility with existing assemblies.
