1812Y5000392MSTE03

Overview

The Knowles Syfer 1812Y5000392MSTE03 is a feed-through multilayer ceramic capacitor designed for surface mount applications. It features a capacitance of 3900 pF with a DC voltage rating of 500 V. The component utilizes an X7R dielectric material and operates within a temperature range of -55°C to +125°C. It is housed in an 1812 (4532 metric) package and includes a 50 mA current rating.

Feature Summary

Integrated feed-through architecture providing combined capacitance and filtering capabilities
Flexible terminal design engineered to reduce stress on board-flex sensitive substrates
High-voltage rating suitable for demanding power circuit environments

Applications

Automotive electronics requiring AEC-Q200 compliance
Power supply input/output filtering stages
Board-flex sensitive circuit assemblies

Procurement Notes

Verify the specific suffix MSTE03 against official manufacturer documentation to confirm the feed-through configuration and terminal specifications. Ensure compatibility with PCB footprint requirements for this unique component type before procurement.

Selection Notes

Select this component when high-voltage filtering and mechanical reliability are required. The flexible terminals mitigate cracking risks during board flexing, making it distinct from standard rigid-terminal MLCCs in similar packages.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which emphasizes mechanical robustness. The 1812Y prefix indicates the 1812 case size and voltage class, while the specific model denotes its specialized feed-through function within the high-reliability capacitor portfolio.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify pinout and electrical characteristics carefully if considering alternative feed-through capacitors.
