1812Y0500683MSTE03

Overview

The Knowles Syfer 1812Y0500683MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in an 1812 package. It features a capacitance of 68 nF with a ±20% tolerance and a DC voltage rating of 50 V. The component utilizes X7R dielectric material and incorporates FlexiCap technology with nickel barrier terminations for enhanced mechanical reliability. It is AEC-Q200 qualified and functions as an X2Y capacitor, providing integrated common-mode noise suppression capabilities within the passive device structure.

Feature Summary

• Integrates X2Y three-terminal architecture for simultaneous differential and common-mode filtering
• FlexiCap flexible termination design reduces stress on PCB pads during thermal cycling
• Nickel barrier layer prevents tin whisker growth and solder joint degradation
• AEC-Q200 qualification ensures suitability for automotive electronic applications

Applications

• Automotive infotainment system power distribution networks
• High-reliability industrial control board decoupling
• Noise-sensitive signal line filtering in vehicle electronics

Procurement Notes

Verify the complete part number including the suffix to confirm specific termination and packaging configurations. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain sources provide valid traceability records for AEC-Q200 certified components used in regulated industries.

Selection Notes

Select this component when board space constraints require combined decoupling and EMI filtering functions. The X2Y topology offers superior high-frequency performance compared to discrete two-terminal capacitors. Evaluate mechanical flexibility requirements against standard rigid-termination MLCCs to determine if FlexiCap benefits outweigh potential cost differences.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, designed for high-reliability environments where mechanical shock resistance is critical. The 1812 footprint provides a balance between capacitance density and physical robustness. Integration of X2Y technology allows designers to reduce component count by merging filtering and storage roles into a single package.

Replacement Considerations

Direct substitutes include other 1812 X2Y capacitors from manufacturers such as TDK or Murata. Verify that replacement parts maintain identical terminal configuration and electrical ratings. Cross-reference AEC-Q200 certification requirements if the application mandates automotive-grade validation.
