0805Y0250393MXTE07

Overview

The Knowles Syfer 0805Y0250393MXTE07 is a three-terminal feed-through capacitor designed for surface-mount applications. It features an 0805 (2012 metric) package with a capacitance of 0.039 µF and a voltage rating of 25 VDC. The component utilizes X7R dielectric material and offers a tolerance of ±20%. It incorporates a nickel barrier structure with 100% tin terminations, providing robust solderability and mechanical stability for high-reliability circuit designs.

Feature Summary

• Three-terminal EMI filter architecture for enhanced noise suppression
• Nickel barrier construction with 100% tin terminations for reliable soldering
• X7R dielectric material ensuring stable performance across operating temperatures

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive digital circuits
• EMI suppression in automotive electronic control units

Procurement Notes

Verify the complete part number including suffixes to ensure correct termination and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference datasheet revisions to validate electrical parameters against current design requirements.

Selection Notes

Select this component when board space constraints require an 0805 footprint but superior filtering performance is needed compared to standard two-terminal MLCCs. The three-terminal design minimizes parasitic inductance, making it suitable for high-speed data lines where signal integrity is critical.

Part Context

This component belongs to the Knowles Syfer Syfer® family of high-reliability ceramic capacitors. The series specializes in EMI filtering solutions that combine small form factors with effective noise attenuation capabilities for modern compact electronic devices.

Replacement Considerations

Direct substitutes include other 0805 three-terminal feed-through capacitors with matching 25V ratings and similar capacitance values. Verify terminal configuration and mounting pad layout compatibility before substitution.
