1812Y2000104MSTE03

Overview

The Knowles Syfer 1812Y2000104MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) featuring an X7R dielectric and AEC-Q200 automotive qualification. It offers a capacitance of 100 nF with a ±20% tolerance, rated for 200 V DC. The component utilizes the FlexiCap technology with a nickel barrier electrode structure to enhance mechanical robustness against cracking. Housed in a standard 1812 (4532 metric) package, it integrates X2Y architecture for superior electromagnetic interference suppression.

Feature Summary

• X2Y architecture provides integrated common-mode noise filtering within a single compact component
• FlexiCap construction with nickel barrier electrodes ensures high resistance to mechanical stress and board flexing
• AEC-Q200 certification confirms suitability for demanding automotive electronic environments

Applications

• Automotive infotainment system power distribution networks
• Electronic control unit input/output signal line decoupling
• High-density PCB layouts requiring combined filtering and energy storage

Procurement Notes

Verify the complete part number including the suffix to ensure correct termination and packaging specifications. Confirm that the procurement channel provides original manufacturer documentation to validate authenticity. Check for specific handling requirements related to the FlexiCap technology during assembly processes.

Selection Notes

Select this component when design requirements demand both high capacitance density and robust mechanical performance in automotive applications. The X2Y configuration simplifies circuit design by replacing multiple discrete components. Ensure voltage derating aligns with operational conditions to maintain reliability over the specified temperature range.

Part Context

This device belongs to the Knowles Syfer Y-series, which specializes in X2Y capacitors combining three terminals in one package. The series targets industries requiring reliable EMI suppression and power integrity. The 1812 footprint allows for space-constrained designs while maintaining high voltage ratings typical of the Syfer portfolio.

Replacement Considerations

Direct substitutes must match the 1812 package, 200V rating, 100nF value, and X2Y topology. Verify compatibility with FlexiCap mechanical properties if board flexing is a concern. Cross-reference AEC-Q200 status to ensure equivalent automotive qualification levels.
