1812Y2000563MSTE03

Overview

The Knowles Syfer 1812Y2000563MSTE03 is a surface-mount X2Y capacitor featuring a 1812 (4532 metric) package. It provides a capacitance of 0.056 µF with a voltage rating of 200V DC. The component utilizes an X7R dielectric and includes AEC-Q200 qualification for automotive reliability. Key structural features include FlexiCap technology and a nickel barrier electrode system, designed to enhance mechanical robustness and electromagnetic interference suppression in compact circuit layouts.

Feature Summary

• X2Y architecture integrates three terminals into a single SMD footprint for superior common-mode noise filtering.
• FlexiCap construction combined with a nickel barrier enhances resistance to mechanical stress and soldering thermal shock.
• AEC-Q200 certification ensures compliance with rigorous automotive electronic component reliability standards.

Applications

• Automotive electronics requiring AEC-Q200 qualified components
• High-density PCB designs needing integrated EMI suppression
• Common-mode noise filtering in sensitive signal lines

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and packaging specifications. Confirm RoHS compliance status and specific reel quantities directly with authorized distributors or the manufacturer prior to ordering, as supply chain conditions may vary.

Selection Notes

Select this component when high-frequency common-mode noise attenuation is required within a constrained surface-mount area. The X2Y topology offers superior performance compared to discrete filter arrangements. Ensure the 200V DC rating and X7R temperature characteristics align with the target circuit's operational environment and voltage stress levels.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in robust multilayer ceramic capacitors. The 1812Y series specifically denotes X2Y configurations, distinguishing them from standard MLCCs by providing inherent differential-to-common-mode conversion capabilities for enhanced signal integrity protection.

Replacement Considerations

Direct substitutes must match the X2Y terminal configuration, 1812 package dimensions, and 200V rating. Verify that alternative parts also possess AEC-Q200 qualification if used in automotive applications. Standard MLCCs cannot replace this component due to the lack of integrated X2Y filtering functionality.
