Procurement Notes

Verify the specific suffix configuration against official manufacturer documentation to confirm terminal count and termination material specifications. Ensure compatibility with existing PCB footprints designed for three-terminal components. Cross-reference datasheet revisions to validate electrical parameters and RoHS compliance status prior to integration into production schedules.

Selection Notes

Select this component when superior EMI attenuation is required alongside mechanical resilience against substrate deformation. The three-terminal design offers improved high-frequency performance over conventional capacitors. Evaluate the 2 A current rating and 100 VDC voltage limit to ensure adequate margins for the target application environment and operational loads.

Part Context

This part belongs to the Syfer FlexiCap series, which specializes in multilayer ceramic capacitors engineered for extreme mechanical reliability. The series is distinguished by its ability to endure board flexing and extensive thermal cycling without cracking, making it suitable for demanding industrial and automotive environments where standard MLCCs might fail.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 270 nF capacitance, 100 VDC rating, and three-terminal EMI filter topology. Verify that alternative components support the same FlexiCap or equivalent flexible termination technology to maintain mechanical reliability standards.
