Overview
The B82789C0113N002 is a surface-mount data line choke from the B82789 series, manufactured by EPCOS (TDK Electronics). It features an inductance of 11 µH and a rated current of 300 mA. The component supports a rated voltage of 42 V AC or 80 V DC, with a maximum DC resistance of 25 Ω. Designed for automotive applications, it holds AEC-Q200 qualification and operates within a temperature range of -55°C to +125°C. The package dimensions are 4.5 mm x 3.2 mm x 3.0 mm.
Feature Summary
- AEC-Q200 qualified for automotive reliability
- Compact surface-mount design for space-constrained layouts
- Dual-function common-mode filtering capability
Applications
- CAN bus signal line protection
- Automotive data communication interfaces
- High-temperature electronic circuit filtering
Procurement Notes
Verify the specific suffix 'N002' against official TDK documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the procurement channel provides traceability to EPCOS/TDK Electronics manufacturing records. Cross-reference the AEC-Q200 certification details with the latest datasheet revision to validate automotive-grade specifications.
Selection Notes
Select this component when designing circuits requiring robust common-mode noise suppression for differential data lines in automotive environments. The 300 mA rating suits low-current signal paths rather than power delivery. Consider the 11 µH inductance value for target frequency attenuation requirements. Verify that the 80 V DC withstand voltage aligns with the system's electrical isolation needs.
Part Context
This part belongs to the B82789C0/S0 series of data and signal line chokes. These components are engineered specifically for protecting sensitive communication lines against electromagnetic interference. The series utilizes advanced winding techniques to achieve high impedance in common-mode signals while maintaining signal integrity for differential transmission.
Replacement Considerations
Consult official TDK substitution guides for compatible alternatives within the B82789 series. Verify pin compatibility and inductance tolerance before replacing. No direct public substitute part numbers are confirmed in the provided source material.
