Overview
The Knowles Syfer 1206Y2000393MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) featuring a 0.039 µF capacitance with ±20% tolerance. It operates at a rated DC voltage of 200V and utilizes X7R dielectric material, ensuring stability across a temperature range of -55°C to +125°C. The component is housed in a standard 1206 (3216 metric) package with dimensions of 3.20mm x 1.60mm. It incorporates FlexiCap technology with nickel barrier end terminations to enhance mechanical reliability.
Feature Summary
- FlexiCap flexible termination design reduces stress on the capacitor body during board flexing
- Nickel barrier end terminations provide enhanced solderability and corrosion resistance
- X2Y internal architecture offers integrated filtering capabilities within a single compact package
Applications
- Automotive electronics requiring AEC-Q200 qualification
- Circuit boards sensitive to mechanical flexure and vibration
- High-reliability signal conditioning and noise suppression circuits
Procurement Notes
Verify the specific suffix MSTE03 against official Knowles Syfer documentation to confirm the presence of nickel barrier terminations and X2Y configuration. Ensure compatibility with reflow soldering profiles specified for FlexiCap components. Confirm RoHS compliance status through current manufacturer declarations prior to integration into production lines.
Selection Notes
Select this component when high voltage handling (200V) and mechanical durability are critical. The X2Y structure provides superior common-mode noise attenuation compared to standard MLCCs. Verify that the 1206 footprint accommodates the required clearance and spacing rules for the target application environment.
Part Context
This part belongs to the Knowles Syfer 1206Y series, which specializes in high-reliability capacitors for demanding environments. The series integrates FlexiCap technology to address failure modes associated with board strain. The 1206Y2000393MSTE03 specifically targets applications needing robust performance under thermal and mechanical stress.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult official Knowles Syfer catalogs for equivalent X2Y or FlexiCap variants with matching electrical specifications.
