Overview
The Knowles Syfer 1206Y1000272MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in a 1206 package. It features X7R dielectric with a capacitance of 2.2 nF and a tolerance of ±20%. Rated for 100 VDC, it operates between -55°C and +125°C. The component utilizes FlexiCap termination with a nickel barrier and holds AEC-Q200 qualification.
Feature Summary
- X7R dielectric material provides stable capacitance characteristics across the operating temperature range.
- FlexiCap termination structure incorporates a nickel barrier to enhance mechanical reliability against board flexure.
- AEC-Q200 qualified for automotive electronics applications requiring high reliability.
Applications
- Automotive electronic circuits
- High-reliability general-purpose filtering
- Decoupling applications in flexible substrates
Procurement Notes
Verify the specific suffix STE03 against official datasheets to confirm the presence of the nickel barrier and FlexiCap termination. Ensure the voltage rating and capacitance values match the design requirements before procurement. Confirm availability status as supply may be restricted in certain regions.
Selection Notes
Select this component when automotive qualification and mechanical robustness are required. The X7R dielectric offers higher capacitance density than Class 1 types while maintaining better stability than Y5V. The FlexiCap termination is essential for applications subject to mechanical stress or board bending.
Part Context
This part belongs to the Knowles Syfer FlexiCap series, designed specifically to mitigate cracking risks in MLCCs caused by PCB flexure. The 1206 case size balances footprint constraints with capacitance needs. The nickel barrier distinguishes it from standard tin-terminated variants.
Replacement Considerations
Substitutes must match the 1206 package, 100V rating, X7R dielectric, and FlexiCap/Nickel Barrier termination. Verify AEC-Q200 compliance if used in automotive contexts. Generic X7R capacitors without the nickel barrier may fail under mechanical stress.
