Overview
The AWCU00453226223TT2 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 -40°C to +125°C. The component has an inductance of 22 µH at 100 kHz and an impedance of 1.2 kOhms at 10 MHz. It supports a maximum DC current of 200 mA with a maximum DC resistance of 1 Ohm. The package dimensions are 4.5 mm x 3.2 mm x 2.6 mm, and it holds AEC-Q200 qualification.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- Ferrite core construction for effective noise suppression
- Compact surface-mount design suitable for space-constrained PCBs
Applications
- Automotive CAN bus systems
- Signal line filtering
- Power supply noise reduction
Procurement Notes
Verify the specific suffix TT2 against official datasheets to confirm packaging details and RoHS compliance status. Ensure the ordering quantity matches the manufacturer's reel specifications. Confirm that the intended application environment falls within the specified operating temperature range of -40°C to +125°C before finalizing procurement.
Selection Notes
Select this component when a compact, AEC-Q200 qualified common mode choke is required for automotive signal lines. Compare the 22 µH inductance and 200 mA current rating against circuit requirements. Consider the 1.2 kOhms impedance at 10 MHz for high-frequency noise attenuation needs in constrained spaces.
Part Context
This part belongs to the AWCU series of common mode chokes from Pulse Electronics. These components are engineered for automotive environments, offering reliable performance in harsh conditions. The series provides various inductance values while maintaining consistent physical dimensions for standardized PCB layouts.
Replacement Considerations
Check for direct substitutes within the AWCU series with matching 4.5x3.2mm footprints. Verify equivalent AEC-Q200 qualification and similar electrical parameters such as 22 µH inductance and 200 mA current handling capacity.
