Overview
The Knowles Syfer 1812Y2000332MXTE03 is a surface-mount multilayer ceramic capacitor (MLCC) featuring an X7R dielectric and a 3.3 nF capacitance with ±20% tolerance. It operates at a DC voltage rating of 200 VDC within the 1812 (4532 metric) case size. The component utilizes FlexiCap technology with a nickel barrier for flexible terminals, ensuring reliability under mechanical stress. It meets AEC-Q200 automotive qualification standards and functions across a temperature range of -55°C to +125°C.
Feature Summary
- FlexiCap flexible terminal design with nickel barrier for enhanced board flex resistance
- AEC-Q200 qualified for automotive electronics applications
- X2Y architecture providing integrated decoupling and filtering capabilities
Applications
- Automotive electronic control units requiring high reliability
- Board-flex sensitive circuit designs
- High-frequency noise suppression in automotive systems
Procurement Notes
Verify the specific suffix MXTE03 against official datasheets to confirm the inclusion of X2Y functionality and FlexiCap terminals, as standard 1812Y series parts may lack these features. Ensure procurement channels source directly from authorized distributors to guarantee AEC-Q200 certification validity and prevent counterfeit components.
Selection Notes
Select this component when board flex durability is critical due to its soft terminal construction. The X2Y configuration offers superior electromagnetic interference suppression compared to standard capacitors. Confirm that the 200V rating and 3.3nF value align with the target circuit requirements before integration.
Part Context
This part belongs to the Knowles Syfer 1812Y series, which specializes in high-reliability MLCCs for demanding environments. The series integrates proprietary FlexiCap technology to mitigate failure risks associated with PCB bending. The 1812Y2000332MXTE03 specifically combines this mechanical robustness with X2Y three-terminal architecture for advanced signal integrity management.
Replacement Considerations
Direct substitutes must match the 1812Y2000332MXTE03 specifications, including X2Y topology, FlexiCap terminals, and AEC-Q200 status. Generic 1812 X7R capacitors are not suitable replacements due to the absence of flexible terminals and specialized filtering characteristics.
