0805Y0500122MJTE07

Overview

The Knowles Syfer 0805Y0500122MJTE07 is a three-terminal X7R dielectric multilayer ceramic capacitor (MLCC) designed for surface mount applications. It features a 0805 (2012 Metric) package with a capacitance of 1.2 nF and a tolerance of ±20%. The component is rated for a DC voltage of 50V and includes a nickel barrier termination structure. This configuration supports its function as an EMI filter within compact electronic assemblies.

Feature Summary

• Three-terminal architecture providing enhanced electromagnetic interference filtering capabilities
• Nickel barrier termination structure ensuring reliable solderability and connection integrity
• X7R dielectric material offering stable capacitance performance across standard operating temperature ranges

Applications

• High-frequency noise suppression in sensitive signal lines
• Power supply decoupling requiring low parasitic inductance
• EMI filtering in compact consumer electronics assemblies

Procurement Notes

Verify the specific suffix 'MJTE07' against official manufacturer documentation to confirm the three-terminal EMI filter configuration and nickel barrier termination. Ensure compatibility with board flex-sensitive designs if applicable, as this series often utilizes flexible terminations. Cross-reference datasheet S02A or equivalent for precise mechanical dimensions and reliability standards before finalizing procurement specifications.

Selection Notes

Select this component when integrated EMI filtering is required without additional discrete components. The three-terminal design offers superior high-frequency performance compared to standard two-terminal MLCCs. Confirm that the 0805 footprint accommodates the specific terminal layout. Evaluate the X7R dielectric characteristics against the circuit's thermal environment to ensure capacitance stability under operational conditions.

Part Context

This part belongs to the Knowles Syfer FlexiCap™ series, which specializes in robust MLCCs for demanding environments. The 0805Y series denotes a 50V rating within the 0805 package size. The MJTE07 suffix specifically identifies the three-terminal EMI filter variant with nickel barrier terminations, distinguishing it from standard two-terminal capacitors in the same family.

Replacement Considerations

Direct substitutes must match the three-terminal EMI filter topology and 0805 footprint. Verify that alternative parts maintain the 1.2 nF capacitance, 50V rating, and X7R dielectric. Ensure replacement components support similar parasitic inductance reduction for effective high-frequency noise suppression.
