Procurement Notes

Verify the specific ordering suffix and pin configuration against official datasheets before procurement. Confirm that the component meets required thermal and electrical ratings for the target application environment. Check for availability status as manufacturing status may vary. Ensure compliance with relevant safety standards for the intended deployment region.

Selection Notes

Select this component when through-hole mounting is required for robust mechanical stability. Consider the 250mA current limit and 4Ω resistance for circuit design compatibility. Evaluate the 2kV withstand voltage capability against system isolation needs. Compare physical footprint constraints with available board space.

Part Context

This part belongs to the TLF9 series of common mode chokes from Taiyo Yuden. It is distinct from surface mount RF inductors or power inductors in the manufacturer's portfolio. The component serves specialized roles in EMI reduction rather than energy storage or RF tuning applications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference options through official manufacturer channels if direct replacement is necessary.
