Overview
The AWCU00453226513TM2 is a surface-mount common mode choke manufactured by Pulse Electronics, designed for automotive applications. It features a ferrite core and operates within a temperature range of -50°C to +150°C. The component has an inductance of 51 µH and an impedance of 3.5 kOhms at a test frequency of 100 kHz. It supports a maximum DC current of 230 mA with a maximum DC resistance of 1 Ohm. The physical dimensions are 4.5 mm x 3.2 mm x 2.6 mm, and it is available in reel, cut tape, or MouseReel packaging formats.
Feature Summary
- Designed specifically for automotive CAN bus systems
- AEC-Q200 qualified for automotive reliability standards
- Compact surface-mount package suitable for space-constrained PCBs
Applications
- Automotive CAN Bus Systems
- Common Mode Choke Applications
- Automotive Electronic Control Units
Procurement Notes
Verify the specific ordering suffix and packaging configuration (Reel, Cut Tape, or MouseReel) required for your production needs. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the AEC-Q200 qualification aligns with your automotive project requirements before finalizing procurement.
Selection Notes
Select this component when high-temperature operation up to 150°C is required for automotive environments. The 51 µH inductance provides effective noise filtering for CAN bus lines. Consider the 230 mA current rating to ensure adequate headroom for signal integrity without saturation. The small footprint allows integration into dense automotive circuit boards.
Part Context
This part belongs to the AWCU series of common mode chokes from Pulse Electronics. The series offers various inductance values tailored for automotive data line protection. The AWCU00453226513TM2 variant specifically targets higher impedance requirements compared to lower inductance options in the same family.
Replacement Considerations
Check for other AWCU series parts with similar inductance and current ratings if exact substitution is needed. Verify that any alternative maintains the AEC-Q200 qualification and compatible operating temperature range for automotive use.
