Procurement Notes

Verify the complete manufacturer part number including all suffix characters against official distributor catalogs before ordering. Confirm that the specific package configuration matches your automated placement equipment requirements. Ensure the X7R temperature coefficient and 100V rating align with your circuit design specifications. Check current supply status as availability may vary by region.

Selection Notes

Select this component when board flex durability is critical for the application environment. The 1206 case size provides a balance between capacitance density and physical robustness. Consider the X7R dielectric characteristics for general purpose filtering where stable capacitance over moderate temperature ranges is required. Verify that the 10% tolerance meets the circuit's precision requirements.

Part Context

This capacitor belongs to the Knowles Syfer FlexiCap family, which specializes in MLCCs with enhanced mechanical resilience. The 1812Y prefix indicates the base product line, while the specific suffixes define the voltage, capacitance, termination style, and barrier materials. This series targets industries demanding high reliability under mechanical stress conditions.

Replacement Considerations

Direct substitutes must match the 1206 case size, 100V rating, 56nF capacitance, X7R dielectric, and flexible terminal type. Verify that any alternative component also holds AEC-Q200 certification if used in automotive contexts. Ensure the replacement maintains the same nickel barrier construction for compatibility.
