0805J0250392MXTE07

Overview

The Knowles Syfer 0805J0250392MXTE07 is a three-terminal multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 3.9 nF with an X7R dielectric and a DC voltage rating of 25 VDC. The component operates within a temperature range of -55°C to +125°C and offers a tolerance of ±20%. Housed in a standard 0805 (2012 metric) package, it utilizes nickel barrier end terminations with 100% tin plating. This configuration supports high-frequency EMI filtering applications.

Feature Summary

• Three-terminal architecture provides enhanced high-frequency electromagnetic interference suppression capabilities compared to standard two-terminal designs.
• X7R dielectric material ensures stable capacitance performance across a wide operational temperature range from -55°C to +125°C.
• Nickel barrier termination structure with 100% tin plating offers reliable solderability and corrosion resistance for surface mount assembly.

Applications

• High-frequency electromagnetic interference filtering in electronic circuits
• Power supply input/output decoupling for noise reduction
• Signal line protection in sensitive communication equipment

Procurement Notes

Verify the specific suffix MXTE07 to confirm the three-terminal EMI filter variant, as standard MLCCs share similar base codes but lack the shielding structure. Ensure compatibility with PCB footprints designed for three-terminal components, which differ physically from standard two-terminal 0805 capacitors. Confirm RoHS compliance status through official manufacturer documentation prior to integration.

Selection Notes

Select this component when superior high-frequency noise attenuation is required over standard MLCCs. The three-terminal design minimizes parasitic inductance, making it suitable for RF and high-speed digital applications. Verify that the circuit layout accommodates the distinct pad configuration required for the shielded terminal connections.

Part Context

This part belongs to the Knowles Syfer general type MLCC family, specifically engineered for EMI suppression. Unlike standard capacitors, the three-terminal construction integrates a grounded shield between the input and output terminals to divert high-frequency noise effectively.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Any replacement must match the three-terminal form factor, 3.9 nF capacitance, 25V rating, and X7R dielectric characteristics.
