Procurement Notes
Verify the specific datasheet version before procurement, as manufacturing status may change. Confirm that the through-hole package dimensions match your PCB footprint requirements. Ensure the 1 A current rating meets your circuit's peak load demands without saturation. Check for any regional tariff implications if shipping to the United States, as indicated in distributor notices.
Selection Notes
Select this component when common mode noise suppression is required in low-current DC or AC power lines. The 350 µH inductance value offers a balance between noise filtering and physical size. Ensure the operating temperature range aligns with your system environment. Verify that the through-hole lead spacing fits your assembly process capabilities.
Part Context
This part belongs to TDK's UF series of common mode chokes, which are widely used for EMI suppression in consumer electronics and industrial equipment. The series typically offers various inductance values and current ratings to suit different power line requirements. These components are essential for meeting regulatory emissions standards in electronic devices.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult TDK technical support for potential alternatives if this component is discontinued or unavailable.
