1806Y1000393MJTE07

Overview

The Knowles Syfer 1806Y1000393MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a capacitance of 0.039 µF with a tolerance of ±20% and utilizes X7R dielectric material. The component is rated for a maximum DC voltage of 100V and operates within a temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) package, it incorporates flexible terminals to enhance board flex sensitivity performance.

Feature Summary

• Flexible terminal construction reduces stress on the PCB during mechanical deformation.
• X7R dielectric provides stable capacitance characteristics across the operating temperature range.
• High reliability design suitable for demanding electronic environments.

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Boardflex sensitive circuit assemblies
• General high-reliability surface mount applications

Procurement Notes

Verify the specific ordering suffix against official Knowles Syfer documentation to confirm terminal type and packaging configuration. Ensure the selected variant matches the required flexibility and voltage ratings for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when board flex sensitivity is a critical design constraint due to its flexible termination technology. The X7R dielectric offers a balance of volumetric efficiency and temperature stability for general-purpose filtering or decoupling. Confirm that the 100V rating and 0.039 µF capacitance align with the circuit requirements and thermal environment specifications.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in MLCCs with compliant terminations. The series targets industries where standard rigid terminations may fail under mechanical stress, such as automotive and industrial sectors. The 1806Y base indicates the case size and voltage class within the manufacturer's broader portfolio of high-reliability ceramic capacitors.

Replacement Considerations

Direct substitutes must match the 1806 case size, 100V rating, 0.039 µF capacitance, X7R dielectric, and flexible terminal structure. Verify that any alternative component maintains equivalent AEC-Q200 qualification if automotive use is intended. Generic MLCCs with rigid terminations are not suitable replacements due to differing mechanical stress profiles.
