Overview
The AWCU00453226104TM2 is a two-line common mode choke manufactured by Pulse Electronics, designed for surface mount technology (SMD/SMT) applications. It features a ferrite core and operates within a temperature range of -40°C to +125°C. The component has an inductance of 100 µH at 1 MHz and offers an impedance of 5.8 kOhms. It supports a maximum DC current of 200 mA with a maximum DC resistance of 2 Ohms. The device is AEC-Q200 qualified and housed in a compact package measuring 4.5 mm x 3.2 mm x 2.6 mm.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- Ferrite core construction for effective noise suppression
- Surface mount design for automated PCB assembly
Applications
- Automotive CAN bus systems
- Automotive LIN bus systems
- In-vehicle network signal line protection
Procurement Notes
Verify the specific suffix TM2 against official datasheets to confirm reel packaging and tape specifications. Ensure compatibility with standard SMD reflow soldering profiles. Confirm that the AEC-Q200 qualification meets the specific reliability requirements of the target automotive application before finalizing procurement decisions.
Selection Notes
Select this component when designing circuits requiring 100 µH inductance for high-frequency noise attenuation on differential data lines. Consider the 200 mA current rating and 2 Ohm DCR for power loss calculations. The unshielded design requires careful PCB layout to minimize electromagnetic interference coupling to adjacent traces.
Part Context
This part belongs to the AWCU series of automotive-grade common mode chokes from Pulse Electronics. These components are engineered specifically for robust performance in harsh automotive environments. The series provides various inductance values to suit different bus speeds and noise profiles while maintaining a consistent footprint for design flexibility.
Replacement Considerations
Direct substitutes must match the 100 µH inductance, 200 mA current rating, and 4.5x3.2 mm footprint. Verify that any alternative component also holds AEC-Q200 certification and maintains similar impedance characteristics at 1 MHz to ensure equivalent noise suppression performance.
