1206Y1000103MSTE03

Overview

The Knowles Syfer 1206Y1000103MSTE03 is a surface-mount feedthrough capacitor featuring X7R dielectric and a 10 nF capacitance. It operates within a -55°C to +125°C range and supports a DC voltage rating of 100 VDC. The component utilizes a 1206 (3216 metric) package with three terminals and soft termination technology. It is epoxy mountable, AEC-Q200 rated, and designed for board flex sensitivity applications.

Feature Summary

• Integrated feedthrough filter design for noise suppression
• Soft termination construction to withstand board flex stress
• Epoxy mountable capability for enhanced mechanical stability

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Circuits sensitive to PCB bending or flexing
• High-reliability surface mount filtering applications

Procurement Notes

Verify the specific suffix MSTE03 against official datasheets to confirm the inclusion of soft termination and epoxy mountable features. Ensure the application environment remains within the specified -55°C to +125°C operating temperature range. Confirm that the 100 VDC rating aligns with circuit requirements before integration.

Selection Notes

Select this component when board flex resistance is critical due to its soft termination structure. The feedthrough configuration provides integrated filtering in a compact 1206 footprint. Verify compatibility with epoxy mounting processes if mechanical reinforcement is required for the assembly line.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in multilayer ceramic capacitors with flexible terminations. The series addresses reliability issues caused by mechanical stress on rigid components during PCB assembly and operation.

Replacement Considerations

Direct substitutes must match the 1206 feedthrough form factor, X7R dielectric, and soft termination characteristics. Generic MLCCs lack the integrated filtering and flex protection.
