1806J0250204MXTE07

Overview

The Knowles Syfer 1806J0250204MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features an 1806 case size with a capacitance of 200 nF and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material, providing stable performance across a wide temperature range from -55°C to +125°C. Tolerance is specified at ±20%. This specific variant is configured as a three-terminal EMI filter, offering enhanced electromagnetic interference suppression capabilities compared to standard two-terminal capacitors.

Feature Summary

• Three-terminal architecture provides superior high-frequency noise attenuation and electromagnetic interference filtering.

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive digital circuits
• EMI suppression in automotive electronic control units

Procurement Notes

Verify the complete part number including the suffix to ensure correct termination and packaging specifications. Confirm that the three-terminal footprint matches the design layout, as it differs from standard MLCCs. Check RoHS compliance status against current regulatory requirements for the target market. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to reflow soldering.

Selection Notes

Select this component when integrated EMI filtering is required without occupying additional board space for discrete filters. The three-terminal design offers better high-frequency performance than standard two-terminal capacitors in the same package. Consider the 50V rating relative to circuit operating voltages to ensure adequate margin. Evaluate thermal management needs given the X7R dielectric characteristics within the specified temperature range.

Part Context

This component belongs to the Knowles Syfer high-reliability MLCC family, specifically engineered for demanding environments. The 1806J series denotes the case dimensions and voltage class. The MXTE07 suffix indicates specific termination materials and tape-and-reel packaging. These capacitors are widely used in aerospace, defense, and industrial sectors where long-term stability and noise immunity are critical.

Replacement Considerations

Direct substitutes must match the 1806 case size, 200nF capacitance, 50V rating, X7R dielectric, and three-terminal EMI filter configuration. Verify compatibility with existing PCB footprints due to the distinct terminal arrangement of three-terminal components.
