1206Y1000222MSTE03

Overview

The Knowles Syfer 1206Y1000222MSTE03 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface mount applications. It features a 1206 (3216 metric) case size with a capacitance of 2.2 nF and a DC voltage rating of 100 V. The component utilizes X7R dielectric material with a tolerance of ±20%. It incorporates FlexiCap technology with a nickel barrier to enhance mechanical robustness against board flexing. The device is AEC-Q200 qualified for automotive use and operates within a temperature range of -55°C to +125°C.

Feature Summary

• FlexiCap design with nickel barrier for enhanced resistance to board flex stress
• AEC-Q200 qualification for automotive reliability standards
• X7R dielectric providing stable performance across wide temperature ranges

Applications

• Automotive electronics requiring high reliability
• Circuit boards susceptible to mechanical flexing
• High-reliability industrial equipment

Procurement Notes

Verify the specific suffix STE03 to confirm the inclusion of the nickel barrier and FlexiCap termination structure, as these define the mechanical handling characteristics. Ensure the X7R dielectric type aligns with the required capacitance stability for the target application environment. Confirm AEC-Q200 compliance if automotive certification is mandatory for the project.

Selection Notes

Select this component when board flex durability is critical, leveraging its specialized FlexiCap termination. The 1206 package offers a balance between capacitance density and mechanical strength. Consider the X7R dielectric properties for general-purpose decoupling where moderate temperature stability suffices. Verify that the 100V rating meets the circuit's maximum operating voltage requirements.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in MLCCs engineered to withstand mechanical stress during assembly and operation. The 1206Y prefix indicates the standard 1206 footprint dimensions. The MSTE03 suffix denotes the specific termination and packaging configuration associated with the nickel barrier and reel format.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 2.2nF capacitance, 100V rating, and X7R dielectric. Crucially, replacements should offer comparable FlexiCap or equivalent board-flex resistant termination technology to maintain mechanical reliability in sensitive applications.
