1812Y5000563MSTE03

Overview

The Knowles Syfer 1812Y5000563MSTE03 is a high-reliability feed-through multilayer ceramic capacitor (MLCC) designed for surface-mount applications. It features a capacitance of 0.056 µF with a DC voltage rating of 500 VDC. The component utilizes X7R dielectric material and offers a tolerance of ±20%. Housed in an 1812 (4532 metric) package, it incorporates FlexiCap technology with nickel barrier terminations to enhance mechanical robustness. This Class 2 capacitor is engineered for environments requiring high current handling capabilities.

Feature Summary

• Integrated feed-through architecture providing high surge current capability
• FlexiCap termination system with nickel barrier for improved board flex resistance
• X7R dielectric construction ensuring stable performance across operating temperatures

Applications

• Automotive electronics requiring AEC-Q200 compliance
• High-voltage power supply filtering circuits
• Applications sensitive to PCB board flex stress

Procurement Notes

Verify the specific suffix MSTE03 to confirm the inclusion of the nickel barrier and feed-through characteristics, as standard MLCC variants may differ. Ensure compatibility with high-current requirements specified in the datasheet. Confirm RoHS compliance status through official manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when both high voltage isolation and significant surge current handling are required within a compact 1812 footprint. The feed-through design distinguishes it from standard capacitors by allowing current passage through the center conductor. Evaluate thermal management needs against the maximum operating temperature limits defined in the technical specifications.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability ceramic capacitors for automotive and industrial sectors. The 1812Y prefix indicates the 1812 case size family. The product line emphasizes durability under mechanical stress, making it suitable for demanding electronic environments where standard components might fail due to vibration or flexing.

Replacement Considerations

Direct substitutes must match the 0.056 µF capacitance, 500 VDC rating, and feed-through structure. Verify that alternative parts support the same current handling capacity and possess compatible nickel barrier terminations to maintain mechanical reliability in flex-sensitive designs.
