1206J2000393MXTE01

Overview

The Knowles Syfer 1206J2000393MXTE01 is a surface-mount feedthrough capacitor designed for EMI suppression. It features a capacitance of 0.039 µF with a voltage rating of 200 VDC and a current rating of 300 mA. The component utilizes an X7R dielectric material housed in a 1206 (3216 metric) package. It provides insertion loss performance suitable for high-frequency noise filtering applications.

Feature Summary

• Three-terminal SMD architecture enabling effective common-mode noise attenuation
• Feedthrough design allowing direct signal path integration without additional grounding traces
• X7R ceramic dielectric providing stable capacitance characteristics across operating temperatures

Applications

• High-speed data line EMI filtering
• Power supply input noise suppression
• Signal integrity protection in communication interfaces

Procurement Notes

Verify the specific suffix MXTE01 against official datasheets to confirm termination plating and tape-and-reel specifications. Ensure compatibility with standard reflow profiles and check for RoHS compliance status prior to procurement. Confirm availability through authorized distributors as lead times may vary.

Selection Notes

Select this component when space-constrained designs require integrated filtering on signal lines. The 1206 footprint offers a balance between capacitance density and board area. Consider the 300 mA current rating to ensure it meets the operational load requirements of the target circuit without saturation or overheating.

Part Context

This part belongs to the Knowles Syfer EMI Filter series, specifically the three-terminal feedthrough capacitor category. These components are engineered to replace discrete LC filters, reducing component count and PCB layout complexity while maintaining effective high-frequency noise suppression in compact electronic assemblies.

Replacement Considerations

Direct substitutes include other 1206 package feedthrough capacitors from Knowles Syfer with matching 200V ratings and similar capacitance values. Verify pinout compatibility and insertion loss curves before substituting with generic equivalents.
