Overview
The Knowles Syfer 1812Y1000103MSTE03 is a multilayer ceramic capacitor (MLCC) in an 1812 surface-mount package. It features a capacitance of 10 nF with a ±20% tolerance and a DC voltage rating of 100 VDC. The component utilizes X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. It incorporates FlexiCap flexible terminations with a nickel barrier and is AEC-Q200 qualified for automotive reliability.
Feature Summary
- FlexiCap flexible termination technology designed to reduce stress on board-flex sensitive applications
- AEC-Q200 qualification ensuring compliance with automotive electronic component standards
- X2Y internal architecture providing integrated filtering capabilities within the MLCC structure
Applications
- Automotive electronics requiring AEC-Q200 certified components
- Board-flex sensitive circuit designs needing stress-relief terminations
- Signal filtering applications utilizing X2Y topology
Procurement Notes
Verify the specific suffix MSTE03 against official datasheets to confirm the presence of FlexiCap terminations and X2Y architecture. Ensure compatibility with automated placement equipment regarding the flexible terminal structure. Confirm RoHS compliance status through current manufacturer documentation before integration.
Selection Notes
Select this component when board flex compensation is critical for reliability. The X7R dielectric offers higher capacitance density than C0G but with greater temperature dependence. Verify that the 100V rating and 10nF value meet circuit requirements. Consider the 1812 footprint constraints during layout design.
Part Context
This part belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors with compliant terminations. The 1812Y prefix indicates the 1812 case size and X7R dielectric type. The MSTE03 suffix typically denotes specific termination materials and packaging configurations unique to this product line.
Replacement Considerations
Direct substitutes must match the 1812 footprint, 100V rating, 10nF capacitance, X7R dielectric, and FlexiCap/X2Y characteristics. Generic 1812 X7R capacitors without flexible terminations may not be suitable for high-stress board flex environments.
