1206J0500393MXTE01

Overview

The Knowles Syfer 1206J0500393MXTE01 is a three-terminal X7R dielectric feedthrough capacitor designed for surface mount applications. It features a capacitance of 39 nF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes a nickel barrier termination structure with 100% tin plating, housed in a standard 1206 (3216 metric) package measuring 3.2 mm by 3.2 mm. It operates within a temperature range of -55°C to +125°C and is supplied in reel packaging.

Feature Summary

• Three-terminal EMI filter architecture providing integrated noise suppression capabilities
• Nickel barrier termination system ensuring robust solderability and mechanical reliability
• X7R ceramic dielectric material offering stable capacitance characteristics across the operating temperature range

Applications

• High-frequency electromagnetic interference filtering in compact electronic circuits
• Power supply input and output stages requiring common-mode noise reduction
• Signal line protection in telecommunications and computing hardware

Procurement Notes

Verify the specific suffix MXTE01 against official Knowles Syfer documentation to confirm the nickel barrier termination and reel packaging configuration. Ensure compatibility with standard SMT assembly processes and check for any recent product change notices regarding material composition or environmental compliance status before finalizing procurement plans.

Selection Notes

Select this component when a low-profile, three-terminal EMI filter is required for high-frequency noise attenuation in space-constrained designs. The 1206 footprint allows for direct replacement of similar-sized two-terminal capacitors where enhanced filtering performance is necessary without increasing board area.

Part Context

This part belongs to the Knowles Syfer 1206J series of surface mount feedthrough capacitors. These components are engineered specifically for EMI suppression, combining the electrical properties of a capacitor with the structural benefits of a three-terminal design to provide superior high-frequency performance compared to conventional MLCCs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify pinout and dimensional compatibility if considering alternative manufacturers' three-terminal EMI filters.
