Overview
The KEMET SN8S-400JA is a through-hole common mode choke from the SN series, designed for AC line filtering applications. It features an inductance of 46 µH and supports a maximum DC current of 2 A with a maximum DC resistance of 52 mΩ. The component utilizes a ferrite core and operates within a temperature range of -25°C to +105°C. Physical dimensions include a 16 mm diameter and an 8 mm height, with an 8 mm lead pitch.
Feature Summary
- Provides common mode noise suppression for power lines
- Utilizes a ferrite core for effective high-frequency attenuation
- Designed for standard PCB mounting via through-hole technology
Applications
- AC power line filtering
- Power supply input stages
- Electronic equipment EMI reduction
Procurement Notes
Verify the specific suffix JA against official KEMET documentation to confirm exact electrical tolerances and material specifications. Ensure the ordering part number matches the required inductance and current ratings for your circuit design. Cross-reference datasheets for thermal derating curves and mechanical footprint details before finalizing procurement.
Selection Notes
Select this component when a 46 µH inductance at 2 A is required for common mode noise suppression. Consider the 52 mΩ DCR for efficiency calculations and the 16 mm diameter for board space constraints. Verify compatibility with operating temperatures up to 105°C and ensure through-hole assembly processes align with the 8 mm lead pitch specification.
Part Context
This component belongs to the KEMET SN series of normal mode coils and standard filters. These parts are categorized as AC line filters intended for general power applications. The series is characterized by through-hole construction and ferrite core materials, providing reliable performance for electromagnetic interference mitigation in electronic systems.
Replacement Considerations
The SN8S-400 is a related variant within the same series. Verify if the SN8D-400 or SCT47X-400-S2R2B007JV serves as a suitable substitute based on specific inductance and current requirements, ensuring mechanical and electrical parameters match the original design intent.
