1206Y0250223MXTE07

Overview

The Knowles Syfer 1206Y0250223MXTE07 is a Class 2 multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features an X7R dielectric material providing stable capacitance characteristics across varying temperatures. The component has a nominal capacitance of 22 nF with a tolerance of ±20% and a DC voltage rating of 25 VDC. It utilizes the standard 1206 (3216 metric) package dimensions, measuring 3.2 mm in length, 1.6 mm in width, and 1.6 mm in height. The device incorporates FlexiCap™ flexible terminations to enhance mechanical reliability under stress.

Feature Summary

• Incorporates FlexiCap™ flexible termination technology to absorb board flexing stresses and prevent cracking.
• Features a nickel barrier layer structure within the termination system for enhanced solderability and corrosion resistance.
• Utilizes X7R dielectric material to maintain capacitance stability over a wide operating temperature range.

Applications

• EMI filtering in high-density electronic circuits
• Board-flex sensitive applications requiring mechanical robustness
• General-purpose decoupling in consumer electronics

Procurement Notes

Verify the complete part number including the suffix 'E07' to ensure correct reel packaging configuration. Confirm that the specific FlexiCap™ and nickel barrier construction matches the design requirements for EMI filtering and mechanical stress relief. Cross-reference the manufacturer datasheet for precise dimensional tolerances and recommended reflow soldering profiles to ensure proper assembly integrity.

Selection Notes

Select this component when circuit designs require EMI suppression capabilities combined with mechanical durability in compact form factors. The 1206 package allows for higher capacitance values compared to smaller footprints while maintaining compatibility with standard SMT processes. Ensure the 25 VDC rating provides sufficient margin for the maximum operating voltage in the target application environment.

Part Context

This component belongs to the Knowles Syfer 1206Y series, which specializes in high-reliability MLCCs featuring specialized termination technologies. The series is engineered to address common failure modes associated with rigid terminations in modern PCB assemblies. The specific model integrates advanced barrier layers to improve long-term performance in demanding electronic environments.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 22 nF capacitance, 25 VDC rating, X7R dielectric, and specifically the FlexiCap™ flexible termination with nickel barrier construction. Generic 1206 X7R capacitors without flexible terminations may not provide equivalent mechanical reliability in flex-sensitive applications.
