0805J1000392MXTE07

Overview

The Knowles Syfer 0805J1000392MXTE07 is a three-terminal feed-through multilayer ceramic capacitor designed for high-frequency noise suppression. It features a capacitance of 3900 pF, rated for 100 V DC and a continuous current of 1 A. The component utilizes an X7R dielectric within a standard 0805 (2012 metric) surface-mount package. Its internal structure integrates a central conductor passing through the dielectric layers, providing superior electromagnetic interference filtering compared to standard two-terminal capacitors.

Feature Summary

• Three-terminal feed-through architecture for enhanced high-frequency noise attenuation
• Integrated center conductor enables direct signal path routing with minimal parasitic inductance
• X7R dielectric material provides stable capacitance characteristics across operating temperatures

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF circuit noise suppression

Procurement Notes

Verify the specific suffix and terminal configuration against the official datasheet to ensure compatibility with the intended PCB footprint. Confirm that the 1 A current rating aligns with the operational requirements of the target circuit. Check for RoHS compliance status and moisture sensitivity level prior to procurement to prevent handling issues during assembly.

Selection Notes

Select this component when low parasitic inductance is critical for maintaining signal integrity in high-speed applications. The three-terminal design offers better performance than standard MLCCs for EMI suppression. Ensure the 100 V rating exceeds the peak voltage in the application. Consider the physical size constraints of the 0805 package relative to available board space.

Part Context

This part belongs to the Knowles Syfer general-purpose multilayer ceramic capacitor family. It is specifically engineered as a feed-through type, distinguishing it from standard parallel-plate MLCCs. The product line focuses on providing reliable filtering solutions for sensitive electronic circuits requiring compact form factors and robust electrical performance.

Replacement Considerations

Direct substitutes must match the 3900 pF capacitance, 100 V rating, and three-terminal feed-through structure. Standard two-terminal 0805 capacitors are not functionally equivalent due to higher parasitic inductance. Verify pinout compatibility if considering alternative manufacturers offering similar feed-through designs.
