Procurement Notes
Verify the specific suffix 'R25044' against official KEMET documentation to confirm the exact inductance and current ratings. Ensure the through-hole footprint dimensions match the target PCB layout. Confirm RoHS compliance status via the latest datasheet revision before integration into regulated products.
Selection Notes
Select this component when a 4.4 mH inductance and 2.5 A current handling are required for common mode noise reduction. The wide temperature range makes it suitable for environments with thermal variability. Verify that the 0.09 ohm DC resistance meets the voltage drop constraints of the specific power supply design.
Part Context
This part belongs to the KEMET SSHB21HS series of common mode chokes. The series offers various inductance and current combinations tailored for AC line filtering. The R25044 designation specifically identifies the 4.4 mH variant within this product family.
Replacement Considerations
Cross-reference with other SSHB21HS variants if different inductance or current values are needed. Ensure any substitute maintains the same through-hole package and voltage rating.
