1812Y2000683MSTE03

Overview

The Knowles Syfer 1812Y2000683MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in an 1812 package. It features a capacitance of 0.068 µF with a ±20% tolerance and a DC voltage rating of 200V. The component utilizes X7R dielectric material and is AEC-Q200 qualified for automotive reliability. It incorporates FlexiCap termination technology with a nickel barrier to enhance mechanical robustness against board flexing. This X2Y configuration provides integrated EMI suppression capabilities within the passive device structure.

Feature Summary

• X2Y architecture integrating three terminals for simultaneous common-mode and differential-mode noise attenuation
• FlexiCap termination system with nickel barrier to prevent cracking under mechanical stress
• AEC-Q200 qualification ensuring reliability for demanding automotive electronic environments

Applications

• Automotive infotainment and display driver circuits
• Engine control unit (ECU) power distribution networks
• Advanced driver-assistance systems (ADAS) signal conditioning

Procurement Notes

Verify the specific suffix MSTE03 matches the required FlexiCap termination and X2Y configuration, as standard MLCCs lack these features. Confirm AEC-Q200 compliance is mandatory for the target automotive application. Check RoHS status and lead-free solderability requirements against current manufacturing standards before finalizing procurement specifications.

Selection Notes

Select this component when board space is limited but high-frequency EMI filtering is critical. The X2Y design replaces multiple discrete capacitors, reducing footprint. Ensure the 200V rating exceeds peak circuit voltages. Verify that the X7R temperature stability meets operational range requirements compared to C0G alternatives if precision is paramount.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, designed for high-reliability applications where mechanical integrity is as important as electrical performance. The X2Y variant specifically addresses electromagnetic interference challenges in compact modern electronics by combining decoupling and filtering functions into a single passive element.

Replacement Considerations

Direct substitutes include other 1812 X2Y capacitors from manufacturers like TDK or Murata, provided they match the 0.068µF value and 200V rating. Verify terminal compatibility and thermal characteristics. Generic X7R MLCCs cannot replace this part due to the absence of the integrated X2Y filtering topology.
