0805J0500473MXTE07

Overview

The Knowles Syfer 0805J0500473MXTE07 is a three-terminal feed-through multilayer ceramic capacitor (MLCC) designed for surface-mount applications. It features a capacitance of 0.047 µF with a DC voltage rating of 50 VDC and a tolerance of ±20%. The component utilizes an X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a compact 0805 (2012 metric) package, it incorporates a metal frame construction with flexible end terminations to enhance mechanical reliability during soldering.

Feature Summary

• Three-terminal feed-through architecture provides superior high-frequency noise attenuation compared to standard two-terminal capacitors.
• Metal frame construction ensures robust mechanical integrity and reliable performance under thermal stress.
• Flexible soft end terminations reduce the risk of cracking during PCB mounting and thermal cycling.

Applications

• High-frequency EMI filtering in sensitive electronic circuits
• Power supply input/output decoupling for noise suppression
• Signal line filtering in communication equipment

Procurement Notes

Verify the specific suffix 'E07' against official manufacturer documentation to confirm reel packaging specifications and terminal plating details. Ensure compatibility with automated pick-and-place equipment regarding the 0805 footprint dimensions. Cross-reference the X7R dielectric characteristics with application thermal requirements to validate long-term stability.

Selection Notes

Select this component when high-frequency noise suppression is critical and space constraints require a low-profile SMD solution. The three-terminal design offers lower equivalent series inductance (ESL) than standard MLCCs. Consider the X7R dielectric's temperature coefficient if operating conditions vary significantly beyond room temperature.

Part Context

This part belongs to the Knowles Syfer XT series of general-type MLCCs. It is distinct from standard two-terminal capacitors due to its integrated ground connection via the center terminal, which enhances shielding effectiveness. The 0805 form factor allows for dense PCB layouts while maintaining electrical performance.

Replacement Considerations

Direct substitutes include other 0805 three-terminal feed-through capacitors with matching 50V ratings and similar capacitance values. Verify that alternative parts maintain the same metal frame construction and flexible termination style to ensure mechanical compatibility.

FAQ

What is the primary advantage of the three-terminal design over standard MLCCs?

The three-terminal design connects the center terminal directly to ground, providing a shorter path for high-frequency noise currents and significantly reducing equivalent series inductance (ESL).

How does the metal frame construction benefit the component?

The metal frame provides enhanced mechanical strength and thermal conductivity, improving reliability during soldering processes and operation in high-temperature environments.
