1812Y5000682MJTE03

Overview

The Knowles Syfer 1812Y5000682MJTE03 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features an X7R dielectric material providing stable capacitance characteristics across a wide temperature range from -55°C to +125°C. The component offers a nominal capacitance of 6800 pF with a tolerance of ±20%. It is rated for a DC voltage of 500 VDC and utilizes a flexible terminal construction to enhance mechanical durability. The physical dimensions conform to the standard 1812 (4532 metric) package size, ensuring compatibility with automated assembly processes.

Feature Summary

• Flexible terminal construction for enhanced board flex sensitivity
• High reliability classification for demanding environments
• X7R dielectric for stable performance across operating temperatures

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Board-flex sensitive circuit designs
• High-voltage signal coupling applications

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct termination and tolerance specifications. Confirm availability status through authorized distributors as supply levels may vary. Ensure storage conditions comply with moisture sensitivity level requirements prior to reflow soldering. Cross-reference part numbers carefully to distinguish between similar series variants.

Selection Notes

Select this component when high voltage handling and mechanical flexibility are required in a compact footprint. The X7R dielectric provides a balance of capacitance density and temperature stability suitable for general-purpose high-voltage filtering. Consider the flexible terminals if the application involves significant PCB stress or warping during operation.

Part Context

This component belongs to the Knowles Syfer FlexiCap™ series, which specializes in capacitors with soft or flexible terminations. This series is engineered to withstand mechanical stress that typically causes failure in standard rigid-termination MLCCs. The 1812Y series designation indicates the 1812 case size and high-voltage capability within the product line.

Replacement Considerations

Direct substitutes must match the 1812 package, 500V rating, 6800pF capacitance, and X7R dielectric. Verify that alternative parts also feature flexible terminals if board flex resistance is critical. Check for equivalent AEC-Q200 qualification if automotive use is intended.
