1206Y0500182MSTE03

Overview

The Knowles Syfer 1206Y0500182MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) featuring an X2Y architecture. It provides a capacitance of 1800 pF with a tolerance of ±20% and operates at a rated voltage of 50V. The dielectric material is X7R, ensuring stability across a temperature range of -55°C to +125°C. This component utilizes the FlexiCap termination system with a nickel barrier for enhanced mechanical reliability.

Feature Summary

• X2Y three-terminal architecture integrates filtering functions within a single compact package
• FlexiCap flexible termination design reduces stress on the ceramic body during board flexing
• Nickel barrier layer protects internal electrodes from solder wicking during reflow processes
• AEC-Q200 qualification ensures suitability for demanding automotive electronic applications

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Circuits sensitive to printed circuit board flexure
• High-density surface mount layouts needing integrated EMI suppression
• Power supply input/output filtering stages

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation before ordering. Confirm that the specific FlexiCap and X2Y variants match your schematic requirements. Check current availability status as automotive-grade components may have restricted distribution channels or longer lead times depending on the region.

Selection Notes

Select this component when space constraints require combining decoupling and filtering in one footprint. The X2Y structure offers superior common-mode noise rejection compared to standard two-terminal capacitors. Ensure the PCB layout supports the three-terminal configuration to realize the intended electromagnetic interference performance characteristics effectively.
