Procurement Notes

Verify the complete part number including the suffix MSTE03, as variations indicate different termination materials or packaging. Confirm RoHS compliance status through official datasheets before integration. Check for specific handling instructions related to the flexible termination structure during assembly. Ensure compatibility with standard SMT reflow profiles specified by the manufacturer.

Selection Notes

Select this component when board flex reliability is critical due to its flexible termination design. Choose the X2Y configuration for applications requiring integrated common-mode filtering without additional components. Consider the 1206 footprint constraints and 100V rating against circuit requirements. Verify that the ±20% tolerance meets the circuit's precision needs compared to tighter tolerance alternatives.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in MLCCs with flexible terminations to enhance mechanical durability. The 1206Y prefix denotes the 1206 case size and general product line characteristics. The series is engineered for high-reliability applications where standard rigid terminations might fail under mechanical stress.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 100V rating, 3300pF value, and X2Y architecture. Verify if alternative parts offer compatible FlexiCap flexibility or if rigid terminations are acceptable for the specific application environment.
