Procurement Notes
Verify the specific suffix TT2 against official Pulse Electronics documentation to confirm reel packaging and tape specifications. Ensure the part number matches the required 11 µH inductance and 250 mA current rating for your design. Cross-reference the AEC-Q200 certification status directly with the manufacturer's latest datasheet to confirm compliance with automotive quality standards before finalizing procurement.
Selection Notes
Select this component when designing for automotive CAN bus networks requiring compact footprint solutions. The 4.5x3.2 mm SMD package suits space-constrained PCB layouts. Verify that the 250 mA current rating aligns with the signal line requirements. The wide operating temperature range makes it suitable for harsh automotive environments where standard commercial components may fail.
Part Context
This part belongs to the AWCU series of automotive common mode chokes from Pulse Electronics. The series is characterized by its small form factor and high-temperature capability. These components are specifically engineered to meet the rigorous demands of modern automotive electronic systems, providing reliable electromagnetic interference suppression in critical communication buses.
Replacement Considerations
Check for direct substitutes within the AWCU series with matching 11 µH inductance and similar current ratings. Verify pin compatibility and mechanical dimensions if replacing with other manufacturers' automotive-grade common mode chokes. Ensure any alternative part also holds AEC-Q200 certification for equivalent automotive reliability.
