Procurement Notes

Verify the specific inductance tolerance and DC resistance values against the official manufacturer datasheet prior to integration. Confirm that the thermal rating aligns with the operational environment requirements. Ensure the through-hole footprint matches the target PCB layout specifications exactly.

Selection Notes

Select this component when high current handling capability is required alongside significant common mode attenuation. The through-hole design offers robust mechanical stability for applications subject to vibration. Evaluate the saturation characteristics to ensure performance under peak load conditions without degradation.

Part Context

This part belongs to the SS21V series of common mode chokes from KEMET. The series provides various inductance and current ratings tailored for different power filtering needs. The SS21V-R180044 specifically addresses applications requiring 1.8 A current capacity with 4.4 mH inductance.

Replacement Considerations

Consult the official KEMET cross-reference documentation for verified substitutes. Ensure any alternative maintains identical inductance, current rating, and physical dimensions to guarantee compatibility.
