B82787C0104H002

Overview

The B82787C0104H002 is a surface-mount common-mode choke from the TDK ACT45B series, designed for automotive CAN bus applications. It features an inductance of 100 µH at 100 kHz and provides an impedance of 5.8 kOhms at 10 MHz. The component supports a maximum DC current of 150 mA with a maximum DC resistance of 2 Ohms. It operates within a temperature range of -40°C to +150°C.

Feature Summary

• Engineered specifically for automotive CAN bus signal integrity protection
• Provides effective common-mode noise suppression via ferrite core technology
• Surface-mount design suitable for automated assembly processes

Applications

• Automotive Controller Area Network (CAN) bus lines
• Data and signal line chokes in vehicle electronics
• High-power motor control cabinet signal interfaces

Procurement Notes

Verify the specific suffix H002 against official TDK documentation to confirm package dimensions and tape/reel specifications. Ensure the supplier provides traceability for automotive-grade components. Cross-reference the impedance value at 10 MHz with system requirements to confirm adequate noise attenuation for the target frequency band.

Selection Notes

Select this component when designing for automotive environments requiring operation up to 150°C. The 150 mA current rating must align with the CAN transceiver peak currents. Consider the 2 Ohm DCR impact on signal voltage levels if driving long cable runs or multiple nodes.

Part Context

This part belongs to the EPCOS/TDK ACT45B series of surface-mount common-mode chokes. These components are widely used in automotive electronics to suppress electromagnetic interference on data lines. The series offers various inductance values tailored for different bus speeds and noise profiles.

Replacement Considerations

Check for direct cross-references in TDK's official replacement guides. Verify that any substitute maintains the 100 µH inductance and 150 mA current rating while fitting the same footprint.
