Procurement Notes
Verify the specific part number against official TAI-TECH documentation to ensure accuracy. Confirm that the required impedance, current rating, and package dimensions match your circuit design requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure storage conditions adhere to the specified operating temperature limits to maintain component integrity.
Selection Notes
Select this component when designing circuits requiring robust common mode noise suppression for high-current applications. The 7A rating makes it suitable for power lines or high-capacity data interfaces. Verify that the 12.00mm x 11.00mm footprint fits within your PCB layout constraints. Consider the AEC-Q200 qualification if the application demands automotive-grade durability and performance standards.
Part Context
This component belongs to the WCM 1211FASV-SERIES-LM family from TAI-TECH. These are wire-wound power common mode filters designed for surface mount technology. The series emphasizes high current handling capabilities and low DC resistance, making them distinct from standard signal-level chokes. The LM suffix typically indicates specific material or packaging variations within the product line.
Replacement Considerations
Consult official TAI-TECH documentation for verified substitute part numbers within the same series. Ensure any replacement maintains identical impedance characteristics, current ratings, and physical dimensions. Cross-referencing with other manufacturers requires careful validation of electrical parameters and mounting specifications.
