0805J0500392MXTE07

Overview

The Knowles Syfer 0805J0500392MXTE07 is a multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 3.90 nF with a tolerance of ±20% and a rated DC voltage of 50V. 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) package, it incorporates a three-terminal architecture with nickel barrier and 100% tin terminations. This specific configuration identifies the device as an EMI filter rather than a standard decoupling capacitor.

Feature Summary

• Three-terminal EMI filter architecture for enhanced noise suppression
• Nickel barrier termination system with 100% tin plating
• X7R dielectric providing stable performance across extended temperature ranges

Applications

• High-frequency electromagnetic interference filtering in compact circuits
• Power supply input/output noise attenuation
• Signal line protection in high-density surface mount assemblies

Procurement Notes

Verify the exact part number suffix MXTE07 to confirm the three-terminal EMI filter variant, as standard MLCCs share similar base codes. Confirm RoHS3 compliance and REACH status through official manufacturer documentation prior to integration. Ensure design compatibility with the specific thermal and mechanical requirements of the nickel barrier termination system.

Selection Notes

Select this component when integrated EMI filtering is required within a limited footprint. The three-terminal design offers superior high-frequency noise attenuation compared to standard two-terminal capacitors. Verify that the ±20% tolerance aligns with circuit requirements and that the 50V rating provides adequate margin for the application's maximum operating voltage.

Part Context

This component belongs to the Knowles Syfer 0805J series, which specializes in high-reliability multilayer ceramic capacitors. The 'J' designation typically indicates a 50V rating within this product family. The specific model integrates filtering capabilities into the standard 0805 form factor, allowing designers to reduce board space by combining decoupling and filtering functions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Replacement requires matching the three-terminal EMI filter specification, X7R dielectric, 50V rating, and 0805 package dimensions.
