1812Y1000823MSTE03

Overview

The Knowles Syfer 1812Y1000823MSTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for high-frequency noise suppression. It features a capacitance of 0.082 µF with a ±5% tolerance and a rated DC voltage of 100V. The component utilizes X7R dielectric material, ensuring stability across an operating temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) surface-mount package, it integrates a built-in terminal structure that allows for direct PCB mounting without additional discrete components.

Feature Summary

• Integrated feed-through architecture provides inherent EMI/RFI filtering capabilities within the passive component form factor.
• Flexible terminal design accommodates board flex requirements, reducing mechanical stress on the ceramic body during assembly or operation.
• AEC-Q200 qualification ensures reliability and performance consistency suitable for demanding automotive electronic environments.

Applications

• Automotive infotainment system power line filtering
• High-speed data interface signal integrity protection
• Board-flex sensitive automotive control modules

Procurement Notes

Verify the specific suffix MSTE03 against official datasheets to confirm the feed-through configuration and terminal type. Ensure compatibility with existing PCB footprints, as feed-through capacitors require distinct pad layouts compared to standard MLCCs. Confirm RoHS compliance status for current production batches.

Selection Notes

Select this component when space-constrained designs require combined decoupling and filtering functions. The 1812 package offers higher capacitance density than smaller cases. Consider the 100V rating for systems with voltage transients exceeding standard 50V rails. Evaluate thermal management needs given the X7R characteristics at elevated temperatures.

Part Context

This part belongs to the Knowles Syfer FlexiCap™ series, which specializes in flexible termination MLCCs. The '1812Y' prefix indicates the 1812 case size and X7R dielectric family. The 'MSTE03' suffix specifically denotes the feed-through variant with soft terminals, distinguishing it from standard parallel-plate capacitors in the same series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Direct replacements must match the feed-through topology and terminal flexibility. Standard MLCCs cannot serve as functional substitutes due to the lack of integrated filtering structure.
