1812Y2000563MJTE03

Overview

The Knowles Syfer 1812Y2000563MJTE03 is a feed-through capacitor designed for high-frequency noise suppression. It features a 200V DC voltage rating and a capacitance of 0.056 µF (56 nF). The component utilizes a 1812 (4532 metric) surface-mount package with a coaxial structure. It is rated for operation within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.

Feature Summary

• Coaxial feed-through architecture provides superior high-frequency EMI/RFI attenuation compared to standard MLCCs.
• AEC-Q200 qualified for reliable performance in demanding automotive electronic environments.
• Nickel barrier termination system enhances solderability and mechanical robustness during assembly.

Applications

• Automotive infotainment and display signal line filtering
• High-speed data interface protection in vehicle control units
• Power supply input/output noise suppression in automotive electronics

Procurement Notes

Verify the specific datasheet revision and lead times directly with authorized distributors, as availability for this feed-through variant may vary. Confirm that the application circuit design accounts for the specific current handling capabilities inherent to the coaxial feed-through structure before finalizing procurement.

Selection Notes

Select this component when standard MLCCs fail to provide adequate high-frequency attenuation due to parasitic inductance. The coaxial design minimizes loop inductance, making it suitable for applications requiring significant noise reduction on signal lines operating at 200V or lower. Ensure board layout accommodates the specific pad geometry required for this package type.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which integrates flexible terminations to reduce stress on the ceramic body. While many parts in the 1812Y series are standard multilayer capacitors, this specific model is a feed-through type, offering distinct electromagnetic interference filtering characteristics rather than simple energy storage.

Replacement Considerations

Direct substitutes must match the 0.056 µF capacitance, 200V rating, and 1812 feed-through form factor. Standard MLCC replacements will not provide equivalent high-frequency noise suppression due to higher parasitic inductance. Verify pinout compatibility if considering alternative feed-through manufacturers.
