0805Y0500123MXTE01

Overview

The Knowles Syfer 0805Y0500123MXTE01 is a multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features a capacitance of 12.00 nF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes an X7R dielectric material, ensuring stability across a wide operating temperature range from -55°C to +125°C. Housed in a standard 0805 (2012 metric) surface-mount package, it incorporates FlexiCap technology with nickel barrier end terminations to enhance mechanical reliability.

Feature Summary

• Three-terminal architecture functions as an integrated EMI filter for noise suppression
• FlexiCap flexible end terminations reduce stress on board flex-sensitive applications
• Nickel barrier plating provides robust solderability and corrosion resistance

Applications

• High-frequency signal line filtering in sensitive electronic circuits
• Power supply input/output stages requiring common-mode noise reduction
• Automotive electronics systems adhering to AEC-Q200 standards

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm terminal structure and termination material. Ensure compatibility with automated pick-and-place equipment regarding the 0805 footprint dimensions. Confirm RoHS compliance status through current manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when simultaneous capacitance and electromagnetic interference suppression are required within a single surface-mount footprint. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Evaluate thermal management requirements against the X7R dielectric characteristics and maximum operating temperature limits.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability MLCCs for demanding environments. The 'Y' designation typically indicates specific construction features distinct from general-purpose lines. As a feed-through type capacitor, it integrates filtering capabilities directly into the circuit layout, simplifying board space utilization while maintaining signal integrity.

Replacement Considerations

Direct substitutes must match the 12 nF capacitance, 50 V rating, X7R dielectric, and three-terminal EMI filter topology. Verify that alternative components support the same 0805 package dimensions and FlexiCap-style flexible terminations to ensure mechanical fit and performance equivalence.
