B82789S0223H002

Overview

The B82789S0223H002 is a surface-mount common-mode choke from the SIMDAD 1812 series, manufactured by EPCOS (TDK). It features an inductance of 22 µH with a tolerance range of -30% to +50%. The component supports a rated DC current of 250 mA and has a maximum DC resistance of 0.58 Ω. It operates within a temperature range of -55 °C to +125 °C or +150 °C depending on specific rating configurations. The device is designed for data line filtering with a rated voltage of 80 V DC and 42 V AC. It complies with AEC-Q200 automotive standards.

Feature Summary

• Provides common-mode noise suppression for differential signal lines
• Automotive-grade reliability certified under AEC-Q200 standards
• Compact 1812 surface-mount package design for space-constrained PCBs

Applications

• CAN-BUS interface protection
• Data line filtering in automotive electronics
• Signal integrity enhancement in high-speed digital circuits

Procurement Notes

Verify the specific suffix code to confirm the exact operating temperature rating, as documentation indicates variations between +125 °C and +150 °C for this series. Ensure the selected variant matches the thermal requirements of the target application environment. Confirm RoHS compliance status through official manufacturer documentation prior to integration.

Selection Notes

Select this component when designing for CAN-BUS or similar differential data lines requiring common-mode noise attenuation. The 22 µH inductance value is suitable for standard automotive communication frequencies. Consider the 250 mA current rating to ensure the component does not saturate during peak operational loads. The 1812 footprint allows for automated surface-mount assembly processes.

Part Context

This part belongs to the B82789S SIMDAD series of data and signal line chokes. These components are engineered for robust performance in harsh environments, particularly within the automotive sector. The series offers various inductance values and current ratings to suit different signal integrity needs while maintaining a consistent small form factor.

Replacement Considerations

Check for B82789S0223N002 if a +150 °C rating is required instead of the standard +125 °C configuration. Verify pinout compatibility and physical dimensions before substituting. Ensure the alternative component meets the same AEC-Q200 qualification standards.
