1812Y5000273MXTE03

Overview

The Knowles Syfer 1812Y5000273MXTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in an 1812 (4532 metric) package. It features X7R dielectric with a capacitance of 27 nF and a DC voltage rating of 500 VDC. The component has a tolerance of ±20% and operates within a temperature range of -55°C to +125°C. It utilizes FlexiCap technology with soft, flexible terminations to enhance board flex sensitivity. The part is AEC-Q200 qualified for automotive applications and includes a nickel barrier electrode structure.

Feature Summary

• FlexiCap technology provides flexible terminations to reduce stress on the capacitor body during PCB bending.
• AEC-Q200 qualification ensures reliability for demanding automotive electronic environments.
• X7R dielectric material offers stable capacitance characteristics across the specified operating temperature range.

Applications

• Automotive electronics requiring high reliability and board-flex resistance
• High-voltage decoupling and filtering circuits
• General-purpose surface mount applications

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm termination type and packaging details. Ensure compatibility with automated placement equipment regarding the 1812 footprint. Confirm RoHS compliance status through current manufacturer documentation before integration into production workflows.

Selection Notes

Select this component when high voltage handling and mechanical robustness are required. The 500V rating suits high-potential circuits. The FlexiCap feature is critical for assemblies subject to mechanical strain. Verify that the ±20% tolerance meets circuit requirements compared to tighter tolerance alternatives.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, designed specifically for automotive and industrial sectors. The 'Y' indicates the 500V rating class, while '273' denotes the 27nF value. It is distinct from standard MLCCs due to its specialized termination structure aimed at preventing cracking under thermal or mechanical stress.

Replacement Considerations

Direct substitutes must match the 1812 package, 500V rating, 27nF capacitance, and X7R dielectric. Verify if alternative parts offer compatible FlexiCap or equivalent flexible termination technologies to maintain board flex integrity in sensitive designs.
