Procurement Notes

Verify the specific suffix 'T1A' against official datasheets to confirm reel packaging specifications. Ensure compatibility with standard 1206 footprint dimensions during PCB layout. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when low parasitic inductance is critical for EMI reduction. The C0G dielectric is suitable for applications requiring minimal capacitance drift. Evaluate the 300 mA current rating against operational load requirements to ensure reliable performance under thermal stress conditions.

Part Context

This part belongs to the W3F series of three-terminal filter capacitors. These components are engineered for superior high-frequency performance compared to standard two-terminal MLCCs. The series utilizes a unique internal structure to minimize ground loop inductance, making them ideal for sensitive RF and high-speed digital circuits.

Replacement Considerations

Direct substitutes within the same series include W3F11A2218AT1A for different capacitance values. Verify pinout compatibility and electrical ratings before substituting with other manufacturers' three-terminal feedthrough capacitors.
