0805Y0500222MXTE01

Overview

The Knowles Syfer 0805Y0500222MXTE01 is a three-terminal feedthrough capacitor designed for surface mount applications. It features a capacitance of 2.2 nF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Its physical dimensions are 2 mm in length, 1.25 mm in width, and 1 mm in height, conforming to the 0805 (2012 metric) package outline.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering performance compared to standard two-terminal capacitors.
• Flexible termination technology accommodates board bending and thermal cycling stress without cracking.

Applications

• High-frequency signal line filtering in electronic circuits
• Power supply input/output noise suppression
• EMI reduction in compact surface mount assemblies

Procurement Notes

Verify the specific suffix TE01 against official datasheets to confirm terminal configuration and packaging details. Ensure compatibility with existing PCB footprint designs, as three-terminal components require distinct layout considerations compared to standard MLCCs. Cross-reference manufacturer documentation for any recent design changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when superior high-frequency attenuation is required in space-constrained designs. The three-terminal structure offers better grounding paths for noise dissipation. Verify that the 50V rating meets circuit requirements and that the X7R temperature stability aligns with operational environmental conditions.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which incorporates proprietary flexible termination materials to improve mechanical reliability under board flexure and thermal stress. The series is engineered for robust performance in demanding environments, including automotive and industrial applications requiring high vibration resistance.

Replacement Considerations

Direct substitutes must match the 0805 footprint, 3-terminal feedthrough topology, 2.2 nF capacitance, and 50V rating. Verify that alternative parts maintain compatible termination flexibility and EMI filtering characteristics to ensure seamless integration without redesigning the filter network.
