Procurement Notes
Verify the specific suffix (NH vs NV) as it may indicate packaging or minor physical differences not affecting electrical function. Confirm availability status, as some distributors list this part as end-of-life or restricted. Ensure the selected variant matches the required lead frame and termination specifications for your assembly process.
Selection Notes
Select this component when a 14 mH inductance is required for common mode noise attenuation at 10 kHz. Ensure the circuit current does not exceed 1.3 A to maintain performance. Verify that the through-hole footprint dimensions align with the PCB layout constraints. Consider the operating temperature range requirements for the final application environment.
Part Context
This component belongs to the KEMET SSR21 series of AC line filters. These chokes are engineered for compact designs requiring effective electromagnetic interference reduction. The series typically offers standardized inductance values suitable for various consumer and industrial electronics applications.
Replacement Considerations
The SSR21NV-13140 is electrically equivalent to the SSR21NH-13140. Both variants share identical electrical specifications including 14 mH inductance and 1.3 A current rating. Substitution should be verified against mechanical footprint requirements if packaging differs.
