Overview
The Knowles Syfer 1206Y1000273MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a capacitance of 0.027 µF with a tolerance of ±20% and a DC voltage rating of 100 VDC. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates FlexiCap technology with nickel barrier end terminations to enhance mechanical robustness against board flexing. This part is AEC-Q200 qualified for automotive use.
Feature Summary
- FlexiCap technology provides enhanced mechanical flexibility to withstand board stress
- Nickel barrier end termination structure improves solderability and reliability
- AEC-Q200 qualification ensures suitability for automotive electronic environments
Applications
- Automotive electronics requiring board-flex sensitivity
- High-reliability general-purpose circuits
- Applications demanding stable capacitance over wide temperature ranges
Procurement Notes
Verify the specific suffix JTE03 against official datasheets to confirm the exact termination and packaging configuration. Ensure compatibility with existing PCB footprints and reflow profiles. Confirm availability through authorized distributors as supply status may vary. Cross-reference the AEC-Q200 certification if automotive compliance is mandatory for the target application.
Selection Notes
Select this component when board flex resistance is critical due to its FlexiCap design. The X7R dielectric offers higher capacitance density than C0G types but exhibits greater capacitance variation with voltage and temperature. Verify that the 100V rating and 0.027 µF value meet circuit requirements. Consider the 1206 package size constraints during layout planning.
Part Context
This part belongs to the Knowles Syfer 1206Y series of high-reliability MLCCs. The series is characterized by specialized termination structures designed to mitigate cracking under mechanical stress. It serves as a robust alternative to standard MLCCs in environments prone to thermal cycling or physical vibration.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult manufacturer catalogs for direct equivalents within the same series or family.
