Overview
The Knowles Syfer 1206Y1000182MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in the FlexiCap series. It features an X7R dielectric with a nominal capacitance of 1800 pF and a tolerance of ±20%. Rated for 100 VDC, this Class 2 component utilizes a 1206 (3216 metric) package size. The device incorporates flexible nickel barrier terminations to enhance mechanical resilience against board flexing stresses.
Feature Summary
- Flexible nickel barrier termination technology designed to withstand mechanical stress from PCB bending
- X7R temperature-stable dielectric material providing consistent capacitance across operating ranges
- Automotive-grade reliability certification compliant with AEC-Q200 standards
Applications
- Board-flex sensitive automotive electronic assemblies
- High-reliability general-purpose circuitry
- Surface-mount applications requiring enhanced mechanical durability
Procurement Notes
Verify the specific ordering suffix STE03 to confirm the presence of the FlexiCap nickel barrier termination structure. Ensure the selected variant matches the required X7R dielectric characteristics and AEC-Q200 compliance level for the target application environment. Confirm package dimensions align with the footprint design.
Selection Notes
Select this component when standard MLCCs are insufficient for environments subject to significant mechanical strain or board flexing. The FlexiCap construction offers superior durability compared to conventional terminations. Verify that the 100V rating and 1800pF value meet the circuit requirements while ensuring compatibility with automated SMD assembly processes.
Part Context
This part belongs to the Knowles Syfer FlexiCap family, which specializes in high-reliability capacitors engineered for harsh conditions. The 1206Y prefix indicates the 1206 case size and 100V voltage class. The MSTE03 suffix specifically denotes the X7R dielectric, ±20% tolerance, and the specialized flexible nickel barrier termination system.
Replacement Considerations
Direct substitutes include other FlexiCap variants within the same series, such as the 1206Y1000182KDT, provided the termination style and reliability grade match the design requirements.
