• High inductance value for effective common mode interference reduction

Applications

• AC line input filtering
• Power supply noise suppression
• Electronic equipment EMI mitigation

Procurement Notes

Verify the specific suffix R041250 against official KEMET documentation to confirm the 125 mH inductance and 0.4 A current rating. Ensure the package type matches the required through-hole footprint dimensions. Confirm RoHS compliance status via the manufacturer's datasheet before procurement.

Selection Notes

Select this component when high inductance is required for low-frequency common mode noise attenuation in AC circuits. The 0.4 A current rating suits moderate power applications. Verify that the 21 mm diameter fits the available board space and that the through-hole leads align with the PCB layout requirements.

Part Context

This part belongs to the SSHB21H series of common mode chokes from KEMET. These components are engineered for robust performance in AC line filtering scenarios. The series offers various inductance values tailored for different noise suppression needs while maintaining standard through-hole compatibility.

Replacement Considerations

Direct substitutes must match the 125 mH inductance, 0.4 A current rating, and 21 mm diameter. Verify equivalent DC resistance and operating temperature range. Cross-reference with other manufacturers' common mode chokes offering similar electrical characteristics and physical dimensions.
