Procurement Notes

Verify the specific suffix 'N1' against official TDK documentation to confirm pin configuration and tape-and-reel specifications. Ensure the selected variant matches the required AEC-Q200 qualification status for automotive deployment. Cross-reference the manufacturer's latest datasheet to validate environmental ratings and mechanical dimensions prior to integration.

Selection Notes

Select this component when designing circuits requiring robust common-mode interference rejection for differential data signals. The 22 µH inductance value offers effective attenuation for specific frequency bands while maintaining low insertion loss. Consider the 0.25 A current rating to ensure the component operates within its thermal limits during peak signal activity without saturation.

Part Context

This device belongs to the B82789C0/S0 family of data and signal line chokes manufactured by EPCOS, now part of the TDK Group. These components are engineered to meet stringent automotive industry requirements, providing reliable electromagnetic compatibility solutions for sensitive electronic interfaces in demanding operational environments.

Replacement Considerations
