1806Y0500273MJTE07

Overview

The Knowles Syfer 1806Y0500273MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) from the FlexiCap series. It features a capacitance of 0.027 µF with a tolerance of ±20% and a rated DC voltage of 50V. The dielectric material is X7R, providing stable performance across an operating temperature range of -55°C to +125°C. The component utilizes a 1806 (4516 metric) package size with dimensions of 4.50mm length, 1.60mm width, and a maximum height of 1.30mm. It incorporates soft termination technology and a nickel barrier to enhance mechanical reliability.

Feature Summary

• Soft termination design reduces stress on electrodes during board flexing
• Nickel barrier end-termination provides enhanced solderability and corrosion resistance
• X7R dielectric ensures stable capacitance over wide temperature variations

Applications

• High-reliability electronic assemblies requiring robust mechanical performance
• Applications sensitive to board flex or mechanical stress
• General-purpose decoupling and filtering in surface-mount circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct termination and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the full part number with official distributor catalogs to avoid substitutions that may differ in termination style or reliability grade.

Selection Notes

Select this component when mechanical durability under board flex is critical. The soft termination feature distinguishes it from standard rigid MLCCs. Ensure the 1806 footprint matches the PCB layout. Verify that the 50V rating and X7R characteristics align with the circuit's electrical requirements and thermal environment.

Part Context

This part belongs to the Knowles Syfer FlexiCap family, which specializes in high-reliability capacitors designed for demanding environments. The series addresses common failure modes associated with mechanical stress in standard ceramic capacitors. It is manufactured by Knowles Syfer, a provider of passive components for industrial and commercial electronics.

Replacement Considerations

Direct replacements must match the 1806 package, 50V rating, 0.027µF capacitance, and X7R dielectric. Crucially, substitute parts must also feature soft termination and nickel barrier terminations to maintain mechanical reliability. Generic 1806 MLCCs without these specific termination technologies are not suitable equivalents.
