0805J0500683MXTE07

Overview

The Knowles Syfer 0805J0500683MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features an X7R dielectric material and offers a nominal capacitance of 0.068 µF with a ±20% tolerance. The component is rated for a DC voltage of 50 VDC and operates within a temperature range of -55°C to +125°C. Housed in a standard 0805 (2012 metric) package, it utilizes flexible end terminations to enhance mechanical durability against board flexing. This part belongs to the XT series, which is engineered for robust performance in demanding electronic environments.

Feature Summary

• Flexible soft end terminations provide enhanced resistance to mechanical stress and board flexing during operation and assembly.
• X7R dielectric material ensures stable capacitance characteristics across a wide operating temperature range from -55°C to +125°C.
• Designed for high reliability in surface-mount applications, suitable for environments requiring durable passive components.

Applications

• High-reliability general-purpose electronics
• Automotive electronic systems
• Industrial control equipment

Procurement Notes

Verify the complete part number including the trailing suffix, as variations such as E07 indicate specific packaging or terminal configurations that may affect compatibility. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required termination style and reel specifications for automated assembly processes. Cross-reference datasheets to validate electrical parameters against design requirements.

Selection Notes

Select this component when a balance of capacitance density and mechanical resilience is required in an 0805 footprint. The X7R dielectric provides higher volumetric efficiency compared to C0G/NP0 types while maintaining acceptable stability for general filtering and decoupling tasks. Consider the flexible termination feature if the application involves significant PCB flexure or thermal cycling stress. Verify that the 50V rating exceeds the maximum circuit voltage with appropriate derating margins.

Part Context

This component is part of the Knowles Syfer XT series, a line of MLCCs specifically engineered for high-reliability markets. The XT series distinguishes itself through specialized construction techniques that improve mechanical strength and long-term stability. Manufactured by Knowles Syfer, these capacitors are widely utilized in sectors where failure rates must be minimized, such as automotive and industrial controls. The 0805 form factor allows for compact circuit board designs without sacrificing performance.

Replacement Considerations

Direct substitutes must match the 0805 package, 50V rating, 0.068µF capacitance, X7R dielectric, and ±20% tolerance. Verify that alternative parts also offer flexible terminations if mechanical stress resistance is critical. Check for equivalent AEC-Q200 qualification if automotive standards apply. Generic X7R 0805 capacitors may lack the specific reliability enhancements of the XT series.
