Procurement Notes

Verify the specific datasheet version when sourcing this component, as manufacturer specifications may undergo revisions over time. Confirm that the four-pin vertical package aligns with your PCB footprint requirements. Ensure the 600 mA current rating and 1.138 Ohm DC resistance meet your circuit's electrical constraints before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits that require robust common mode noise attenuation on AC lines. The 9.9 mH inductance value is suitable for suppressing lower frequency interference. Consider the physical size of 18x16x17.5 mm to ensure adequate clearance on the board. The through-hole construction offers mechanical stability compared to surface mount alternatives.

Part Context

This part belongs to Taiyo Yuden's leaded common mode choke coil series. These components are engineered specifically for AC line applications where reliable noise suppression is critical. The product line emphasizes durability and consistent performance in power filtering roles, distinguishing it from general-purpose inductors or high-frequency RF chokes.
