Overview
The KEMET SSR21NVS-08235 is a through-hole common mode choke from the SSR21NVS series, designed for AC line filtering. It features an inductance of 23.5 mH at 10 kHz and supports a rated current of 0.8 A with a maximum voltage of 250 VAC. The component has a low DC resistance of 420 mOhms and operates within a temperature range of -25°C to +120°C. It provides high impedance for single-phase EMI suppression.
Feature Summary
- Provides effective single-phase EMI filtering for AC power lines
- Features a compact, low-profile through-hole design for easy integration
- Constructed with high insulation resistance for safety compliance
Applications
- AC line input filtering for consumer electronics
- EMI suppression in single-phase power supplies
- Common mode noise reduction in household appliances
Procurement Notes
Verify the specific suffix (NVS) against the official KEMET datasheet to confirm electrical parameters such as inductance tolerance and thermal ratings. Ensure the package type matches the target PCB footprint. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by local regulations.
Selection Notes
Select this component when a 23.5 mH inductance is required for 0.8 A applications. Consider the 250 VAC rating for mains-connected devices. Evaluate the through-hole mounting requirement against available board space. Compare the 420 mOhm DCR against efficiency requirements for the specific power stage.
Part Context
This component belongs to the KEMET SSR21NVS series of common mode chokes. These filters are engineered for high impedance performance in single-phase AC applications. The series offers various inductance values to suit different noise suppression needs while maintaining a small physical profile suitable for dense circuit layouts.
Replacement Considerations
Check for direct substitutes within the SSR21NVS series with matching inductance and current ratings. Verify that any alternative component meets the same 250 VAC and thermal specifications. Ensure mechanical compatibility for through-hole mounting before substitution.
