Procurement Notes

Verify the complete part number against official TDK documentation to ensure correct suffix alignment, as variations may indicate different termination materials or tape-and-reel specifications. Confirm RoHS compliance status directly from the manufacturer's latest datasheet revision to meet regulatory requirements for specific regional markets.

Selection Notes

Select this component when designing circuits requiring high capacitance values in small form factors for power integrity management. Ensure the operating voltage remains below the 6.3 VDC rating and that the expected ripple current does not exceed the 6 A limit to maintain reliability and prevent thermal issues during continuous operation.

Part Context

This component belongs to the TDK YFF series of three-terminal feedthrough capacitors. These devices combine the functions of a capacitor and an inductor to provide superior high-frequency noise attenuation compared to standard two-terminal capacitors. The series is engineered for robust performance in environments demanding strict electromagnetic compatibility standards.

Replacement Considerations

Consult TDK's official cross-reference guides for verified substitutes. Ensure any alternative maintains identical three-terminal topology, 1206 footprint, and comparable electrical ratings to preserve circuit impedance characteristics and mechanical fit.
