1206Y0500823MSTE03

Overview

The Knowles Syfer 1206Y0500823MSTE03 is a multilayer ceramic capacitor (MLCC) in a 1206 surface-mount package. It features an X7R dielectric with a capacitance of 82.00 nF and a tolerance of ±20%. The component has a DC voltage rating of 50V and is AEC-Q200 qualified for automotive reliability. It utilizes FlexiCap technology with a nickel barrier termination to enhance mechanical durability.

Feature Summary

• FlexiCap flexible termination design with nickel barrier for improved board flex resistance
• AEC-Q200 qualification ensuring automotive-grade reliability standards
• X7R dielectric material providing stable capacitance characteristics over temperature

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Circuit boards subject to mechanical stress or flexing
• General-purpose decoupling and filtering in SMD assemblies

Procurement Notes

Verify the specific suffix MSTE03 against official datasheets to confirm the presence of the nickel barrier and FlexiCap termination structure. Ensure procurement channels are authorized, as availability may be restricted in certain regions. Confirm RoHS compliance status through current manufacturer documentation before integration into production.

Selection Notes

Select this component when automotive reliability and mechanical robustness are required in a standard 1206 footprint. The X7R dielectric offers higher capacitance density than Class 1 types but requires consideration of voltage coefficient effects. The FlexiCap feature is critical for applications involving PCB warpage or vibration.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, designed specifically to address failure modes associated with rigid terminations in high-reliability environments. The 1206Y prefix indicates the 1206 metric size family within the broader Syfer portfolio of high-performance ceramic capacitors.

Replacement Considerations

Direct substitutes must match the 1206 size, 50V rating, 82nF value, X7R dielectric, and AEC-Q200 qualification. Verify if alternative suppliers offer equivalent FlexiCap/nickel barrier termination structures to ensure identical mechanical performance under board flex conditions.
