1206Y2000392MXTE03

Overview

The Knowles Syfer 1206Y2000392MXTE03 is a surface-mount multilayer ceramic capacitor (MLCC) featuring an X2Y architecture. It provides a capacitance of 3.9 nF with a ±20% tolerance and a DC voltage rating of 200 V. The component utilizes an X7R dielectric material, ensuring stability across a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates FlexiCap technology for flexible terminations and a nickel barrier layer to enhance reliability under mechanical stress.

Feature Summary

• X2Y three-terminal architecture integrates decoupling and filtering functions within a single compact footprint.
• FlexiCap flexible termination design mitigates stress-induced cracking on board-flexible substrates.
• Nickel barrier construction provides enhanced protection against soldering conditions and environmental factors.

Applications

• High-density digital circuit decoupling
• EMI suppression in signal lines
• Automotive electronics requiring AEC-Q200 compliance

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm terminal plating and barrier specifications. Ensure compatibility with reflow profiles and check for RoHS/REACH compliance status prior to integration. Confirm availability through authorized channels as supply levels may vary.

Selection Notes

Select this component when board flex sensitivity is a primary concern due to its soft termination structure. The X2Y topology offers superior common-mode noise rejection compared to standard capacitors. Verify that the 200V rating meets the peak transient voltage requirements of the target application.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, designed for high-reliability applications where mechanical robustness is critical. The 1206Y prefix indicates the 1206 case size and general product family characteristics within the manufacturer's portfolio.

Replacement Considerations

Direct substitutes must match the X2Y topology, 1206 package, and 200V rating. Standard MLCCs lack the integrated filtering capability. Verify pinout compatibility as X2Y terminals differ from conventional two-terminal designs.

FAQ

What is the electrical function of the third terminal?

The third terminal serves as a ground connection, enabling the X2Y structure to filter both differential and common-mode noise simultaneously.

Is this component suitable for automotive applications?

Yes, the FlexiCap series is typically qualified to AEC-Q200 standards for automotive use.
