Overview
The Knowles Syfer 1812Y1000332MSTE03 is a multilayer ceramic capacitor (MLCC) in the FlexiCap series, designed for board-flex sensitive applications. It features an X7R dielectric with a capacitance of 3.3 nF and a DC voltage rating of 100 V. The component utilizes a nickel barrier termination structure and carries AEC-Q200 qualification. It operates within a temperature range of -55°C to +125°C and is supplied in reel packaging.
Feature Summary
- FlexiCap soft termination technology reduces stress on terminations during PCB flexing
- AEC-Q200 qualified for automotive reliability standards
- X7R dielectric provides stable capacitance across operating temperatures
- Nickel barrier electrode structure ensures robust solderability
Applications
- Automotive electronics requiring high reliability
- Board-flex sensitive circuit assemblies
- General purpose surface mount applications
Procurement Notes
Verify the complete part number including the suffix MSTE03 to confirm the specific termination and packaging configuration. Ensure compatibility with AEC-Q200 requirements if used in automotive contexts. Confirm that the X7R dielectric characteristics meet the thermal stability needs of the target application environment before finalizing procurement.
Selection Notes
Select this component when board flex resistance is critical due to its soft termination design. The 1812 package offers a balance of capacitance density and physical footprint. Verify that the 100V rating and 3.3nF value align with circuit requirements. Consider the X7R temperature coefficient for applications where capacitance drift under varying thermal conditions is acceptable.
Part Context
This component belongs to the Knowles Syfer 1812Y family, which specializes in high-reliability capacitors for demanding environments. The FlexiCap series specifically addresses mechanical stress issues common in modern miniaturized electronics. It serves as a specialized solution within the broader MLCC market for automotive and industrial sectors.
Replacement Considerations
Check for compatible parts within the same FlexiCap series or other manufacturers offering soft-termination MLCCs with matching 1812 dimensions and X7R characteristics. Ensure any substitute maintains AEC-Q200 certification if required by the original design specifications.
