1812Y5000682MXTE03

Overview

The Knowles Syfer 1812Y5000682MXTE03 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a capacitance of 6800 pF with a tolerance of ±20% and a DC voltage rating of 500 VDC. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it incorporates flexible soft terminations to enhance mechanical durability against board flexing. This part is AEC-Q200 qualified, making it suitable for demanding automotive and industrial applications requiring robust reliability.

Feature Summary

• Flexible soft termination design reduces stress on the ceramic body during PCB assembly and operation.
• AEC-Q200 qualification ensures compliance with strict automotive electronic component standards.
• X7R dielectric provides consistent capacitance characteristics over a wide temperature range.

Applications

• Automotive electronics systems requiring AEC-Q200 compliant components
• Circuit boards susceptible to mechanical flexing or vibration
• High-voltage signal coupling and decoupling in industrial equipment

Procurement Notes

Verify the complete part number including the suffix E03, which indicates specific packaging or terminal configurations. Confirm AEC-Q200 certification status if automotive qualification is mandatory for your application. Check current availability as lead times may vary. Ensure compatibility with your PCB footprint dimensions for the 1812 case size. Review datasheet for moisture sensitivity level and reflow soldering profile requirements.

Selection Notes

Select this component when high voltage handling at 500VDC is required alongside mechanical resilience. The X7R dielectric offers a balance of capacitance density and stability compared to Class 1 materials. Consider the flexible terminations if the application involves significant thermal cycling or mechanical stress on the substrate. Compare against standard rigid termination MLCCs if board flex is not a primary concern.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, specialized for high-reliability environments. The 1812Y prefix denotes a 500V rated X7R capacitor within the 1812 package family. The Y series typically targets automotive and industrial sectors where failure rates must be minimized. It represents a shift from traditional rigid-termination capacitors to more mechanically robust solutions.

Replacement Considerations

Direct substitutes must match the 1812 package, 500V rating, 6800pF value, ±20% tolerance, and X7R dielectric. Verify that any replacement also features flexible terminations if mechanical stress is a factor. Ensure the alternative part holds AEC-Q200 qualification if used in automotive contexts. Cross-reference pinout and dimensional tolerances for seamless integration.
