1206Y2000122MXTE03

Overview

The Knowles Syfer 1206Y2000122MXTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 1206 (3216 metric) case size with a nominal capacitance of 1.2 nF and a DC voltage rating of 200 VDC. The component utilizes X7R dielectric material, providing stable performance across a wide temperature range from -55°C to +125°C. It offers a tolerance of ±20% and incorporates FlexiCap technology with a nickel barrier end termination to enhance mechanical robustness against PCB stress. This device is AEC-Q200 qualified for automotive use.

Feature Summary

• FlexiCap flexible end termination design reduces mechanical stress on the ceramic body
• Nickel barrier layer prevents tin whisker growth and solder joint degradation
• AEC-Q200 qualification ensures reliability in demanding automotive environments

Applications

• Automotive electronics systems requiring AEC-Q200 compliance
• High-voltage decoupling and filtering circuits
• General-purpose SMD/SMT mounting in industrial equipment

Procurement Notes

Verify the specific suffix configuration when ordering, as terminal materials and barrier layers define the part's mechanical properties. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure storage conditions maintain component integrity before reflow soldering processes are initiated.

Selection Notes

Select this component when a 200V rating and 1.2nF value are required in a standard 1206 footprint. The X7R dielectric provides sufficient stability for general applications where tight tolerance is not critical. Consider the FlexiCap feature if the application involves significant board flexing or thermal cycling that could damage rigid terminations.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in mechanically robust MLCCs. The series addresses common failure modes related to cracking during assembly or operation. The 1206Y prefix indicates the 1206 case size and X7R dielectric type within the manufacturer's catalog structure.

Replacement Considerations

Direct substitutes must match the 1206 package, 200V rating, 1.2nF capacitance, and X7R dielectric. Verify that alternative parts also offer FlexiCap-style flexible terminations and nickel barriers if mechanical resilience is required. Cross-reference AEC-Q200 qualification if automotive usage is intended.
