0805Y0500273MXTE07

Overview

The Knowles Syfer 0805Y0500273MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 0805 (2012 metric) package with dimensions of 2.00 mm length, 1.25 mm width, and a maximum height of 1.30 mm. The component offers a capacitance of 27 nF with a tolerance of ±20%, rated at 50 V DC. Utilizing X7R dielectric material, it operates within a temperature range of -55°C to +125°C. The part incorporates FlexiCap™ technology with soft nickel barrier terminations to enhance board flex sensitivity performance.

Feature Summary

• FlexiCap™ soft termination technology reduces stress on the capacitor body during PCB bending or thermal cycling.
• Nickel barrier end termination structure provides robust solderability and reliability for surface mount assembly.
• X7R ceramic dielectric ensures stable capacitance characteristics across the specified industrial temperature range.

Applications

• High-reliability general-purpose electronic circuits requiring board-flex sensitive components
• Industrial control systems subject to mechanical vibration or thermal expansion
• Automotive electronics assemblies meeting stringent reliability standards

Procurement Notes

Verify the complete ordering part number including suffixes to ensure correct termination and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Check manufacturer availability as supply constraints may affect delivery schedules. Ensure storage conditions align with lead time limitations to prevent moisture absorption issues before reflow soldering.

Selection Notes

Select this component when board flex sensitivity is critical due to mechanical stress in the application environment. The 0805 footprint allows for compact design while maintaining adequate voltage rating for low-voltage signal paths. Consider the X7R dielectric stability for applications requiring consistent capacitance over varying temperatures. Evaluate the soft termination benefits against standard rigid termination alternatives for improved mechanical durability.

Part Context

This component belongs to the Knowles Syfer FlexiCap™ series of high-reliability MLCCs. The series is engineered specifically for applications where mechanical integrity under board flex conditions is paramount. The 0805 form factor represents a standard industry size balancing capacitance density and physical footprint. These capacitors are widely utilized in sectors demanding long-term operational stability and resistance to mechanical failure modes.

Replacement Considerations

Direct substitutes must match the 0805 package, 27 nF capacitance, 50 V rating, and X7R dielectric. Verify that alternative parts also feature soft termination technology if board flex sensitivity remains a requirement. Cross-reference termination materials and solderability specifications to ensure compatibility with existing assembly processes.
