Procurement Notes
Verify the specific manufacturer datasheet for detailed electrical characteristics and mechanical drawings. Confirm that the component meets all relevant regulatory standards required for your target market. Ensure compatibility with your assembly process regarding mounting type and thermal requirements before finalizing procurement decisions.
Selection Notes
Select this component when a robust solution for high-current common mode noise reduction is required in a small form factor. The 4A rating makes it suitable for power applications where standard signal-line chokes would saturate. Consider the 40 Ohm impedance specification relative to the noise frequencies present in your specific circuit design.
Part Context
This part belongs to Laird-Signal Integrity Products' lineup of passive components designed for electromagnetic interference filtering. Common mode chokes in this series are engineered to attenuate unwanted differential and common mode signals without affecting the desired signal integrity.
