Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm functional attributes. Ensure the selected variant matches the required current rating and termination style for your application. Cross-reference the part number with the latest datasheet to confirm availability status and packaging details before finalizing procurement plans.

Selection Notes

Select this component when high-frequency noise suppression is required alongside standard decoupling functions. The feed-through design reduces parasitic inductance compared to standard MLCCs. Consider the 500V rating and 50mA current capacity during circuit design. Verify compatibility with automated assembly processes due to the specific package dimensions and terminal flexibility.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability capacitors with soft terminations. The 1812Y base designation indicates the case size and voltage class. As a feed-through device, it integrates filtering directly into the mounting footprint, distinguishing it from conventional parallel-plate MLCC structures.

Replacement Considerations
