0805Y0500122MXTE01

Overview

The Knowles Syfer 0805Y0500122MXTE01 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a capacitance of 1200 pF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material and is housed in an 0805 (2012 metric) case size. It operates within a temperature range of -55°C to +125°C and employs flexible soft terminals to reduce mechanical stress on the substrate.

Feature Summary

• Flexible soft terminal construction minimizes mechanical stress on the printed circuit board during thermal cycling or board flexing.
• X7R dielectric material provides stable capacitance performance across a wide operating temperature range.
• Designed for high-reliability environments requiring robust surface-mount ceramic capacitors.

Applications

• High-reliability electronic assemblies
• Applications sensitive to board flexure
• General-purpose surface-mount filtering

Procurement Notes

Verify the complete part number including the suffix E01, as it defines specific packaging or termination characteristics. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required reel quantity and handling specifications for your manufacturing process.

Selection Notes

Select this component when a 1200 pF capacitance at 50 VDC is required in an 0805 footprint. The X7R dielectric offers a balance of capacitance density and stability. The flexible terminal option is critical for designs where mechanical integrity under thermal stress is a primary concern compared to standard rigid terminations.

Part Context

This part belongs to the Knowles Syfer 0805Y series of high-reliability MLCCs. The series is characterized by its use of flexible terminations to enhance durability in demanding environments. It is distinct from standard commercial-grade capacitors by focusing on mechanical resilience and consistent electrical performance over the specified temperature range.

Replacement Considerations

Direct substitutes must match the 0805 package, 50V rating, 1200pF value, X7R dielectric, and flexible terminal type. Verify that any alternative component maintains equivalent reliability standards and physical dimensions to ensure compatibility with existing footprints and assembly processes.

FAQ

What is the dielectric material used in this capacitor?

The 0805Y0500122MXTE01 uses X7R dielectric material, which provides good capacitance stability over a wide temperature range.
