Overview
The Knowles Syfer 1206Y0500222MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in a 1206 package. It features a capacitance of 2200 pF with a ±20% tolerance and an X7R dielectric. The component has a DC voltage rating of 50V and operates within a temperature range of -55°C to +125°C. It utilizes FlexiCap technology with nickel barrier terminations for enhanced reliability.
Feature Summary
- X2Y architecture providing integrated common-mode filtering capabilities
- FlexiCap flexible termination design to mitigate board flex stress
- Nickel barrier layer ensuring robust solderability and connection integrity
Applications
- Automotive electronics requiring AEC-Q200 qualification
- High-reliability industrial control systems
- Data communication equipment signal line protection
Procurement Notes
Verify the specific suffix MSTE03 against official Knowles Syfer documentation to confirm the X2Y configuration and FlexiCap termination type. Ensure compatibility with automated pick-and-place processes due to the 1206 form factor. Confirm RoHS compliance status through current manufacturer declarations before final procurement integration.
Selection Notes
Select this component when space-constrained designs require combined decoupling and EMI suppression functions. The X2Y structure offers superior common-mode noise attenuation compared to standard MLCCs. Evaluate thermal management requirements against the X7R dielectric characteristics and maximum operating temperature limits.
Part Context
This part belongs to the Knowles Syfer FlexiCap series, designed for high-reliability applications. The 1206Y prefix indicates the 1206 case size. The Y0500 segment denotes the 50V DC voltage rating. The 222 code specifies the 2200 pF capacitance value. The MSTE03 suffix identifies the specific termination and packaging configuration.
Replacement Considerations
Direct substitutes must match the 1206 footprint, 50V rating, 2200pF capacitance, and X2Y topology. Verify that alternative components support the same FlexiCap mechanical flexibility and nickel barrier termination requirements for equivalent reliability.
