1206Y0250222MJTE07

Overview

The Knowles Syfer 1206Y0250222MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 2200 pF with a tolerance of ±20% and a rated DC voltage of 25V. The component utilizes an X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Packaged in a standard 1206 (3216 metric) footprint, it incorporates FlexiCap technology with nickel barriers for enhanced reliability.

Feature Summary

• Integrated EMI filtering capability through a three-terminal feed-through architecture
• Flexible termination design utilizing FlexiCap technology to mitigate board stress
• Nickel barrier construction within the electrode structure for improved durability

Applications

• High-frequency noise suppression in sensitive electronic circuits
• EMI filtering applications requiring compact surface-mount solutions
• Boardflex-sensitive designs where mechanical stress relief is critical

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required impedance characteristics and terminal materials. Confirm that the three-terminal feed-through topology aligns with the intended PCB layout constraints. Cross-reference the X7R dielectric specifications to validate thermal stability requirements for the target operating environment before finalizing procurement decisions.

Selection Notes

Select this component when integrated EMI filtering is required without additional discrete filter components. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Ensure the 1206 footprint accommodates the specific pad geometry required for feed-through structures. Evaluate the 25V rating against peak circuit voltages to maintain adequate safety margins during operation.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability multilayer ceramic capacitors. The series emphasizes mechanical robustness through flexible terminations suitable for rigid-flex and boardflex-sensitive applications. The 1206Y prefix indicates the specific case size and family classification within the manufacturer's portfolio of advanced passive components.

Replacement Considerations

Direct substitutes must match the three-terminal feed-through topology and 1206 dimensions. Verify equivalent X7R dielectric properties and 25V ratings. Standard two-terminal capacitors are not functionally equivalent due to differing filtering characteristics.
