1812Y2000392MXTE03

Overview

The Knowles Syfer 1812Y2000392MXTE03 is a multilayer ceramic capacitor (MLCC) in an 1812 surface-mount package. It features X7R dielectric with a capacitance of 3.9 nF and a DC voltage rating of 200 VDC. The component offers ±20% tolerance and operates within a temperature range of -55°C to +125°C. It utilizes FlexiCap technology with nickel barrier terminations for enhanced mechanical reliability.

Feature Summary

• Incorporates FlexiCap technology with nickel barrier terminations to improve board flex sensitivity and mechanical robustness.
• Designed as an X2Y capacitor structure for integrated common-mode noise suppression capabilities.

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Circuit boards susceptible to mechanical stress or flexing
• High-frequency noise filtering applications

Procurement Notes

Verify the specific termination material and series designation against official datasheets, as suffixes indicate distinct structural variations. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the selected packaging format matches assembly line requirements. Cross-reference part numbers to avoid confusion with standard MLCC variants lacking the FlexiCap feature.

Selection Notes

Select this component when board flex resistance is critical due to its specialized termination design. The X2Y configuration provides simultaneous differential and common-mode filtering in a single footprint. Verify that the 200V rating and 3.9nF value align with circuit requirements. Consider the operating temperature range and tolerance specifications for environmental stability.

Part Context

This part belongs to the Knowles Syfer FlexiCap family, engineered for high-reliability applications. The 1812Y prefix denotes the series characteristics, while the specific model number defines the electrical parameters. It represents a specialized solution for automotive and industrial sectors demanding superior mechanical durability compared to standard MLCCs.

Replacement Considerations

Direct substitutes must match the X2Y topology and FlexiCap termination style. Standard 1812 X7R capacitors lack the mechanical benefits and may not fit electrically if X2Y functionality is required. Verify pinout compatibility and physical dimensions before substitution.
