0805Y1000472MXTE07

Overview

The Knowles Syfer 0805Y1000472MXTE07 is a three-terminal multilayer ceramic capacitor (MLCC) designed for surface mount applications. It features a capacitance of 4.7 nF with a tolerance of ±20% and utilizes an X7R dielectric material. The component has a DC voltage rating of 100 VDC and is housed in an 0805 (2012 metric) package. It incorporates FlexiCap technology with nickel barrier end terminations to enhance mechanical reliability. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal EMI filter architecture providing superior high-frequency noise suppression compared to standard two-terminal capacitors.
• FlexiCap flexible terminal construction reduces stress on the ceramic body during board flexing, improving solder joint integrity.
• Nickel barrier end termination structure ensures reliable solderability and prevents tin whisker formation.

Applications

• High-density PCB layouts requiring effective electromagnetic interference filtering in limited space.
• Boardflex-sensitive electronic assemblies where mechanical robustness against substrate deformation is critical.
• Signal line protection in consumer electronics and industrial control systems.

Procurement Notes

Verify that the specific part number includes the 'E07' suffix, which denotes the reel packaging format. Confirm that the application environment does not exceed the specified 100V DC rating or the +125°C maximum operating temperature. Ensure the design accounts for the physical dimensions of the three-terminal footprint to avoid placement errors during assembly.

Selection Notes

Select this component when both EMI filtering performance and mechanical durability are required in a compact form factor. The three-terminal design offers better attenuation characteristics than standard MLCCs. Consider the FlexiCap feature if the target circuit board experiences significant mechanical strain or thermal cycling that could compromise standard rigid terminations.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in mechanically robust ceramic capacitors. The 0805Y prefix indicates the 0805 case size and X7R dielectric type. As a three-terminal device, it functions as an integrated EMI filter rather than a simple energy storage capacitor, distinguishing it from standard single-capacitor components in the same package family.

Replacement Considerations

Direct substitutes must match the 4.7 nF capacitance, 100V rating, X7R dielectric, and specifically the three-terminal EMI filter topology. Standard two-terminal 0805 capacitors are not functionally equivalent due to inferior high-frequency filtering performance. Verify that any alternative also features flexible terminations if boardflex resistance is a design requirement.
