1812Y2000273MSTE03

Overview

The Knowles Syfer 1812Y2000273MSTE03 is a surface-mount multilayer ceramic capacitor designed for high-frequency applications. It features a capacitance of 0.027 microfarads with a voltage rating of 200 volts DC. The component utilizes an X7R dielectric material and offers a tolerance of plus or minus twenty percent. Housed in a standard 1812 (4532 metric) package, it supports SMD/SMT mounting. The device operates within a temperature range of negative fifty-five to one hundred twenty-five degrees Celsius and meets AEC-Q200 automotive standards.

Feature Summary

• Incorporates FlexiCap technology with nickel barrier end terminations to enhance mechanical reliability.
• Features X2Y internal architecture providing simultaneous decoupling and filtering capabilities.
• Complies with AEC-Q200 qualification requirements for automotive electronic components.

Applications

• Automotive electronics requiring board flex sensitivity mitigation
• High-frequency signal decoupling circuits
• Integrated noise suppression in sensitive electronic modules

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm terminal materials and internal structure. Ensure compatibility with automated pick-and-place equipment regarding the 1812 footprint dimensions. Confirm that the X2Y topology aligns with the intended circuit schematic requirements before finalizing procurement orders.

Selection Notes

Select this component when board flex resistance is critical due to its specialized termination design. The X2Y structure offers superior electromagnetic interference reduction compared to standard capacitors. Consider the 200-volt rating and X7R characteristics for stable performance across varying thermal conditions in demanding environments.

Part Context

This part belongs to the Knowles Syfer 1812Y series, which specializes in high-reliability capacitors for automotive and industrial sectors. The series emphasizes mechanical robustness through advanced packaging technologies. It addresses common failure modes associated with standard MLCCs in vibration-prone applications.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 200V rating, 0.027uF value, and X2Y functionality. Verify equivalent AEC-Q200 certification and FlexiCap termination specifications to ensure mechanical and electrical compatibility without redesigning the PCB layout.
