1812Y5000103MSTE03

Overview

The Knowles Syfer 1812Y5000103MSTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a capacitance of 10,000 pF with a 500 VDC rating and operates within a temperature range of -55°C to +125°C. The component utilizes an X7R dielectric and includes integrated filtering capabilities rated at 50 mA. Housed in an 1812 (4532 metric) surface-mount package, it provides effective electromagnetic interference suppression in compact designs.

Feature Summary

• Integrated feed-through architecture combining capacitance and filtering functions
• High current handling capability with 50 mA rating
• Flexible terminal construction for board flex sensitivity
• AEC-Q200 qualified for automotive reliability standards

Applications

• Automotive electronic control units requiring EMI suppression
• Power supply input/output filtering circuits
• Board-flex sensitive high-reliability assemblies
• Compact high-voltage signal conditioning modules

Procurement Notes

Verify the specific MSTE03 suffix configuration against official Knowles Syfer documentation to confirm the feed-through topology and 50 mA rating. Standard MLCC part numbers may lack these integrated filtering characteristics. Ensure design compatibility with the 1812 footprint and thermal requirements before procurement.

Selection Notes

Select this component when simultaneous decoupling and common-mode noise suppression are required in space-constrained environments. The feed-through design reduces parasitic inductance compared to discrete components. Consider the 50 mA current limit and 500 VDC rating during circuit analysis to ensure operational safety under peak load conditions.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which emphasizes mechanical robustness through flexible terminations. The 1812Y base indicates a high-voltage class 2 ceramic capacitor family. The MSTE03 designation specifically identifies the feed-through variant, distinguishing it from standard parallel-plate MLCCs within the same voltage and capacitance range.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific feed-through variant are not available in the provided reference data. Verify cross-compatibility with other 1812 feed-through capacitors based on pinout and current ratings.
