0805Y1000273MXTE07

Overview

The Knowles Syfer 0805Y1000273MXTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 27,000 pF with a tolerance of ±20% and a DC voltage rating of 100V. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in an 0805 (2012 metric) package, it incorporates flexible soft terminals to enhance board flex reliability.

Feature Summary

• Integrated feed-through architecture provides effective EMI filtering in a compact footprint.
• Flexible soft terminal construction reduces mechanical stress on the substrate during board flexing.
• X7R ceramic dielectric ensures stable capacitance performance across the specified operating temperature range.

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• EMI suppression in sensitive electronic circuits

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct dielectric type, termination style, and packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the manufacturing process.

Selection Notes

Select this component when board flex reliability is critical due to its soft terminal design. Ensure the 100V rating and 27,000 pF capacitance align with circuit requirements. Verify that the X7R temperature coefficient meets the thermal stability needs of the application environment.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in MLCCs with flexible terminations. The series addresses reliability issues in applications subject to mechanical stress or board warping, offering a robust solution for modern miniaturized electronics.

Replacement Considerations

Direct substitutes must match the 0805 package, 100V rating, 27,000 pF value, and X7R dielectric. Verify that alternative parts also feature flexible terminals if board flex resistance is required.

FAQ

What is the primary advantage of the soft terminal design?

The soft terminal design significantly improves reliability by absorbing mechanical stress, preventing cracking in the ceramic body during PCB flexing or thermal cycling.

Is this component suitable for high-temperature environments?

Yes, the X7R dielectric allows the component to operate reliably within a temperature range of -55°C to +125°C.
