1206J0250393MXTE07

Overview

The Knowles Syfer 1206J0250393MXTE07 is a multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a 1206 package size with a capacitance of 39 nF and a voltage rating of 25 VDC. The component utilizes X7R dielectric material, providing a tolerance of ±20%. It is constructed as a three-terminal EMI filter with nickel barrier and 100% tin terminations, suitable for high-reliability applications requiring electromagnetic interference suppression.

Feature Summary

• Three-terminal architecture functions as an integrated EMI filter within the capacitor structure
• Nickel barrier termination system ensures robust solderability and mechanical stability
• X7R dielectric composition offers stable capacitance performance across standard operating temperatures

Applications

• Electromagnetic interference filtering in surface mount circuits
• High-reliability electronic assemblies requiring integrated decoupling and filtering
• Applications utilizing nickel barrier termination systems for enhanced durability

Procurement Notes

Verify the specific suffix MXTE07 against official Knowles Syfer documentation to confirm the exact termination and packaging configuration. Ensure compatibility with existing PCB footprints designed for three-terminal EMI filter capacitors rather than standard two-terminal MLCCs. Cross-reference datasheet revisions to validate current manufacturing status and compliance certifications before finalizing procurement plans.

Selection Notes

Select this component when circuit design requires simultaneous capacitance and EMI suppression in a single surface mount footprint. The three-terminal design necessitates specific layout considerations distinct from conventional capacitors. Verify that the 25V DC rating and 39nF value align with the target circuit requirements and that the 1206 package dimensions fit the available board space constraints.

Part Context

This part belongs to the Knowles Syfer 1206J series of high-reliability multilayer ceramic capacitors. The series is characterized by its use of nickel barrier terminations and availability in various configurations, including specialized three-terminal EMI filter variants. These components are engineered for demanding environments where standard capacitors may not provide sufficient noise suppression or reliability.

Replacement Considerations

Direct substitutes must match the three-terminal EMI filter topology, 1206 package, 39nF capacitance, and 25V rating. Standard two-terminal MLCCs are not functionally equivalent due to the lack of integrated filtering capabilities. Verify termination materials and dielectric type to ensure comparable performance characteristics.
