Overview
The Knowles Syfer 1812Y1000562MSTE03 is a Surface Mount Multilayer Ceramic Capacitor (MLCC) in an 1812 package. It features a capacitance of 5.6 nF with ±20% tolerance and a DC voltage rating of 100V. The dielectric material is X7R, providing stable performance across a temperature range of -55°C to +125°C. This component utilizes FlexiCap technology with a nickel barrier for enhanced mechanical reliability. It is certified to AEC-Q200 standards and functions as an X2Y capacitor.
Feature Summary
- X2Y architecture provides integrated common-mode noise suppression
- FlexiCap termination design reduces stress on the ceramic body
- Nickel barrier end-termination ensures robust solderability
- AEC-Q200 qualification supports automotive deployment
Applications
- Automotive electronic circuits requiring board-flex sensitivity
- High-reliability industrial control systems
- Noise suppression in sensitive signal paths
Procurement Notes
Verify the complete part number including the suffix to ensure correct termination and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation before integration. Check current supply availability as distribution may be restricted or limited in certain regions. Ensure storage conditions align with moisture sensitivity level requirements.
Selection Notes
Select this component when high mechanical durability against board flexing is required. The X2Y configuration offers superior electromagnetic interference filtering compared to standard capacitors. Verify that the 100V rating and 5.6nF value meet circuit requirements. Consider the 1812 footprint constraints during layout planning.
Part Context
This device belongs to the Knowles Syfer FlexiCap series, designed for applications demanding high reliability under mechanical stress. The X2Y topology integrates three terminals into a single package to enhance noise filtering efficiency. It serves as a specialized solution for automotive and industrial environments where standard MLCCs may fail due to cracking.
Replacement Considerations
Direct substitutes require matching X2Y topology, 1812 package, and 5.6nF ±20% X7R characteristics. Verify terminal compatibility and AEC-Q200 certification if automotive use is intended.
