1812Y5000683MJTE03

Overview

The Knowles Syfer 1812Y5000683MJTE03 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features an X7R dielectric material providing stable capacitance characteristics across a wide temperature range from -55°C to +125°C. The component offers a nominal capacitance of 0.068 µF with a tolerance of ±20% and a DC voltage rating of 500 VDC. Housed in a standard 1812 (4532 metric) package, it utilizes flexible terminal construction to enhance mechanical durability against board flexing stresses.

Feature Summary

• Flexible terminal construction designed to withstand mechanical stress during board flexing applications
• High reliability classification suitable for demanding electronic environments
• X7R dielectric ensures consistent performance across extended industrial temperature ranges

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Board-flex sensitive circuit assemblies
• High-voltage filtering and decoupling in industrial equipment

Procurement Notes

Verify the complete part number including suffixes when ordering, as variations may exist. Confirm current availability status directly with authorized distributors or the manufacturer, as stock levels fluctuate. Ensure compatibility with existing PCB footprints and reflow soldering profiles specified in the official datasheet before procurement.

Selection Notes

Select this component when high voltage handling and mechanical robustness are required in a compact surface-mount form factor. The flexible terminals make it preferable over standard terminations in applications subject to thermal cycling or mechanical vibration. Verify that the 500V rating and 0.068 µF capacitance meet specific circuit requirements compared to lower voltage or different tolerance alternatives.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability MLCCs with soft termination technologies. The 1812Y prefix indicates the 1812 case size and high-voltage capability within the product line. These capacitors are engineered to address failure modes associated with mechanical stress in rigid ceramic components.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Any replacement must match the 1812 footprint, 500V rating, X7R dielectric, and flexible terminal specifications to ensure functional equivalence.
