1806Y0500104METE07

Overview

The Knowles Syfer 1806Y0500104METE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 1806 case size with a capacitance of 0.1 µF and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. It offers a tolerance of ±20% and incorporates flexible terminal technology to enhance mechanical durability against board flexing.

Feature Summary

• Flexible terminal construction reduces stress on the ceramic body during PCB bending or thermal cycling.
• Nickel barrier layer provides enhanced corrosion resistance and solderability for reliable surface mounting.
• X7R dielectric ensures consistent capacitance stability over a wide industrial temperature range.

Applications

• Automotive electronics requiring AEC-Q200 qualification
• Board-flex sensitive circuit designs
• High-reliability industrial control systems

Procurement Notes

Verify the specific ordering suffix to confirm the presence of the nickel barrier and flexible terminal specifications. Ensure the package type matches your automated assembly requirements. Cross-reference the manufacturer part number with official distributor catalogs to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when board flex resilience is critical for long-term reliability. The 1806 footprint balances capacitance density with mechanical robustness. Verify that the 50V rating exceeds the maximum operating voltage in the target circuit to ensure adequate derating margins under varying thermal conditions.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors with soft terminals to mitigate cracking risks. The 1806Y series indicates a standard 1806 metric footprint with Y-series characteristics. It is distinct from standard rigid-terminal MLCCs by its specialized electrode design aimed at automotive and rugged environments.

Replacement Considerations

Direct substitutes must match the 1806 case size, 50V rating, 0.1 µF capacitance, and X7R dielectric. Flexible terminal and nickel barrier features are essential for equivalent mechanical performance. Generic MLCCs without these specific termination structures may not provide sufficient board flex resistance.
