1206Y2000222MSTE03

Overview

The Knowles Syfer 1206Y2000222MSTE03 is a multilayer ceramic capacitor (MLCC) in a 1206 surface-mount package. It features a capacitance of 2200 pF with a ±20% tolerance and an X7R dielectric material. The component has a rated DC voltage of 200V and operates within a temperature range of -55°C to +125°C. It utilizes FlexiCap technology with a nickel barrier for enhanced reliability.

Feature Summary

• FlexiCap flexible termination design reduces stress on the capacitor body during board flexing
• Nickel barrier layer prevents electrode migration and enhances solderability
• AEC-Q200 qualification ensures suitability for automotive electronic applications

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Circuits sensitive to board flex deformation
• High-reliability surface mount assemblies

Procurement Notes

Verify the specific suffix STE03 confirms the nickel barrier and FlexiCap configuration, as standard Y-series parts may differ. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation before procurement. Ensure the 1206 footprint matches your PCB layout requirements precisely.

Selection Notes

Select this part when high mechanical robustness against board strain is required in automotive environments. The X7R dielectric provides stable capacitance over the operating temperature range. Verify that the 200V rating meets the circuit's maximum voltage demands with appropriate derating margins.

Part Context

This component belongs to the Knowles Syfer 1206Y series of high-reliability MLCCs. The series is designed for demanding applications where standard capacitors might fail due to mechanical stress. The specific model integrates advanced termination technologies to improve durability in vibration-prone environments.

Replacement Considerations

Direct substitutes must match the 1206 package, 2200pF value, 200V rating, X7R dielectric, and AEC-Q200 qualification. Verify that any replacement also includes FlexiCap and nickel barrier features if mechanical flexibility is critical.
