- Signal line protection in electronic equipment
- General purpose filtering in consumer electronics
Procurement Notes
Verify the specific ordering suffix, such as WK1, against the manufacturer's official documentation to ensure correct pinout and mechanical tolerances. Confirm that the required current rating of 400mA aligns with the target circuit design. Check for any recent product discontinuance notifications or business transfer notices issued by Taiyo Yuden regarding this series before finalizing procurement plans.
Selection Notes
Select this component when a through-hole solution is required for common mode noise reduction in low-current applications. Ensure the PCB layout accommodates the 17.00mm x 11.00mm footprint. Verify that the 1.5 Ohm DC resistance does not introduce excessive voltage drop in the specific power rail. Consider the -25°C to 115°C operating range for environmental suitability.
Part Context
This part belongs to the TLF9 series of common mode chokes manufactured by Taiyo Yuden. The series focuses on providing reliable EMI suppression for through-hole mounting applications. It serves as a passive filter component within larger electronic assemblies, distinct from surface mount alternatives.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's official cross-reference documentation for verified equivalents.
