1206J2000393MXTE07

Overview

The Knowles Syfer 1206J2000393MXTE07 is a surface-mount X2Y integrated EMI filter capacitor housed in a 1206 (3216 metric) package. It features a capacitance of 0.039 µF with a voltage rating of 200 VDC and a tolerance of ±20%. The component utilizes an X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Designed as a three-terminal feedthrough device, it incorporates a nickel barrier termination system to provide effective electromagnetic interference suppression in compact circuit layouts.

Feature Summary

• Integrates three-terminal X2Y architecture for enhanced common-mode noise attenuation within a standard surface-mount footprint.
• Utilizes X7R ceramic dielectric to maintain consistent electrical characteristics across wide industrial temperature variations.
• Features nickel barrier terminations to ensure reliable solderability and mechanical stability during reflow processes.

Applications

• Electromagnetic interference filtering in high-density digital logic circuits
• Signal line protection in automotive electronic control units
• Power supply decoupling in sensitive analog measurement equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm terminal composition and packaging configuration. Ensure that the selected variant matches the required voltage derating and thermal management specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a multi-terminal filter solution without adding discrete components. Evaluate the impedance characteristics at the target noise frequencies to ensure adequate attenuation. Confirm compatibility with the assembly process regarding peak reflow temperatures and moisture sensitivity levels defined in the official documentation.

Part Context

This part belongs to the Knowles Syfer X2Y series of integrated passive devices. These components combine filtering and decoupling functions into a single monolithic structure. The series is engineered for applications requiring robust noise suppression in environments where traditional two-terminal capacitors may offer insufficient common-mode rejection or occupy excessive board area.

Replacement Considerations

Direct substitutes include other 1206 package X2Y filters from the same manufacturer family, such as variants with different capacitance values or voltage ratings. Cross-brand replacements must match the physical dimensions, terminal configuration, and electrical ratings to ensure functional equivalence.
