Overview
The KEMET SN8D-400JB is a differential mode choke from the SN-JB series, designed for through-hole PCB mounting. It features an inductance of 80 µH and supports a maximum DC current of 2 A with a maximum DC resistance of 85 mΩ. The component operates within a temperature range of -25°C to +105°C and measures 18.5 mm in length, 15.5 mm in width, and has a specified height.
Feature Summary
- Provides differential mode filtering for power circuits
- Utilizes terminal base style construction for stable mounting
- Supports high current handling capabilities
Applications
- Industrial control circuits
- AC line filters
- Power supply noise suppression
Procurement Notes
Verify the specific package configuration upon ordering, as distributor listings may indicate tray packaging while official datasheets describe a terminal base style. Confirm that the 80 µH inductance and 2 A current rating align with the target circuit requirements before finalizing procurement decisions.
Selection Notes
Select this component when differential mode attenuation is required rather than common mode filtering. Ensure the PCB layout accommodates the through-hole terminal base style and the physical dimensions of 18.5 mm by 15.5 mm. Verify thermal management needs given the +105°C maximum operating temperature limit.
Part Context
This part belongs to the SN-JB series of differential mode chokes manufactured by KEMET. These components are engineered for general-purpose power filtering applications where standard inductance values and moderate current ratings are sufficient for noise reduction in electronic systems.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Evaluate alternative differential mode chokes from other manufacturers based on matching 80 µH inductance, 2 A current rating, and compatible through-hole mounting styles.
FAQ
Is the SN8D-400JB a common mode or differential mode choke?
It is a differential mode choke designed for normal mode filtering applications.
What is the maximum DC current rating for this component?
The maximum DC current rating is 2 A.
