1812Y5000473MXTE03

Overview

The Knowles Syfer 1812Y5000473MXTE03 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 0.047 µF with a DC voltage rating of 500 V and a tolerance of ±20%. Housed in an 1812 (4532 metric) case size, it utilizes flexible termination technology to enhance mechanical durability against board stress.

Feature Summary

• Flexible termination construction enhances resistance to mechanical stress and board bending
• X7R dielectric ensures stable electrical performance across extended temperature ranges
• High voltage rating suitable for demanding power supply applications

Applications

• High-voltage power supply filtering
• Industrial control systems requiring robust passive components
• Automotive electronics meeting stringent reliability standards

Procurement Notes

Verify the specific suffix 'E03' against official manufacturer documentation to confirm exact termination and packaging specifications. Ensure compatibility with assembly processes when transitioning to flexible termination devices. Cross-reference datasheets for precise handling requirements and storage conditions prior to procurement.

Selection Notes

Select this component for applications requiring high voltage isolation and mechanical resilience. The flexible termination design mitigates cracking risks during thermal cycling or PCB flexing. Confirm that the 1812 footprint aligns with existing board layouts and that the 500V rating exceeds operational peak voltages with adequate safety margins.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in MLCCs with proprietary flexible terminations. These components are engineered for superior mechanical performance compared to standard rigid-termination capacitors. The series is recognized for reliability in harsh environments and has qualified for space applications, distinguishing it from general-purpose ceramic capacitors.

Replacement Considerations

Direct substitutes include other FlexiCap variants within the same series, such as 1812Y5000473MXT, provided the E03 suffix does not denote unique functional changes. Verify equivalent capacitance, voltage ratings, and termination flexibility before substitution.
