1812Y2000272MSTE03

Overview

The Knowles Syfer 1812Y2000272MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features an X7R dielectric with a capacitance of 2700 pF and a voltage rating of 200 VDC. The component utilizes the FlexiCap technology with a nickel barrier, providing enhanced mechanical robustness against board flexing stresses. It is certified to AEC-Q200 standards for automotive use and is housed in a standard 1812 (4532 metric) package.

Feature Summary

• FlexiCap technology with nickel barrier for superior resistance to board flex-induced cracking
• AEC-Q200 qualification ensuring reliability in demanding automotive environments
• X7R dielectric material offering stable capacitance characteristics over temperature

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Circuits subject to mechanical stress or board flexing
• High-reliability general-purpose surface mount applications

Procurement Notes

Verify the specific suffix MSTE03 to confirm the inclusion of the FlexiCap nickel barrier structure, as this defines the mechanical performance profile. Ensure the procurement documentation explicitly states AEC-Q200 certification status for automotive validation purposes. Confirm the packaging format matches production line requirements prior to ordering.

Selection Notes

Select this component when mechanical durability under board flex conditions is critical. The X7R dielectric provides a balance of capacitance density and stability suitable for general decoupling. Verify that the 200V rating meets the circuit's maximum operating voltage including transients. The 1812 footprint allows for higher capacitance values compared to smaller packages while maintaining standard mounting compatibility.

Part Context

This part belongs to the Knowles Syfer 1812Y series, which specializes in high-reliability capacitors. The Y-series designation typically indicates specific construction features tailored for rugged environments. This model represents a specific capacitance value within the broader family of automotive-grade MLCCs offered by the manufacturer.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 200V rating, 2700pF capacitance, and X7R dielectric. Crucially, replacements should offer comparable FlexiCap or equivalent board-flex resistant technology if mechanical stress is a design factor. Verify AEC-Q200 certification if used in automotive contexts.
