Procurement Notes

Verify the complete part number including suffixes against official TDK documentation to ensure correct capacitance, voltage rating, and termination specifications. Confirm RoHS compliance status and packaging details directly with authorized distributors or the manufacturer before procurement.

Selection Notes

Select this component when low parasitic inductance is critical for high-frequency signal filtering. The three-terminal design offers superior performance over standard capacitors in suppressing common-mode noise. Ensure the 50V rating meets the circuit's operational requirements and the 0805 footprint aligns with the PCB layout constraints.

Part Context

This component belongs to TDK's YFF series of three-terminal feed-through capacitors. These devices are engineered specifically for protecting sensitive signal lines from electromagnetic interference. The series provides various capacitance values and package sizes to accommodate different frequency response needs and board space limitations.

Replacement Considerations

Consult TDK datasheets for direct equivalents within the YFF series. Verify that any substitute maintains the three-terminal structure and similar parasitic characteristics to ensure consistent filtering performance in the specific application.
