0805Y0250821MXTE01

Overview

The Knowles Syfer 0805Y0250821MXTE01 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features an X7R dielectric material providing stable capacitance characteristics across a wide temperature range of -55°C to +125°C. The component offers a nominal capacitance of 820 pF with a tolerance of ±20% and a DC voltage rating of 25 VDC. Housed in a standard 0805 (2012 metric) package, it utilizes flexible end terminations to enhance mechanical durability.

Feature Summary

• Flexible end terminations reduce stress on the ceramic body during board flexing
• X7R dielectric ensures reliable performance within specified temperature limits
• High-reliability construction suitable for sensitive electronic assemblies

Applications

• Board-flex sensitive circuit designs
• High-reliability industrial electronics
• Automotive embedded systems

Procurement Notes

Verify the specific suffix MXTE01 against official manufacturer documentation to confirm termination style and packaging configuration. Ensure compatibility with automated assembly processes by checking reel specifications. Confirm RoHS compliance status through current datasheets prior to integration into production workflows.

Selection Notes

Select this component when board flexibility is a primary concern due to its soft terminal design. The X7R dielectric provides a balance of capacitance density and stability for general filtering or decoupling tasks. Ensure the 25V rating meets the maximum operating voltage requirements of the target circuit application.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors with flexible terminations. The series targets applications where mechanical strain from PCB warping or vibration could cause failure in standard rigid-termination MLCCs. The 0805Y prefix indicates the standard footprint dimensions.

Replacement Considerations

Direct substitutes must match the 0805 footprint, 25V rating, 820pF value, and specifically feature flexible/soft terminations. Standard rigid-termination equivalents may not provide adequate protection against board flex stress.
