1806Y0500823MJTE07

Overview

The Knowles Syfer 1806Y0500823MJTE07 is a three-terminal feed-through multilayer ceramic capacitor designed for surface mount applications. It features an 1806 (4516 metric) case size with a capacitance of 0.082 µF and a voltage rating of 50 VDC. The component utilizes X7R dielectric material, offering a tolerance of ±20%. It incorporates FlexiCap technology with nickel barrier end terminations to enhance mechanical reliability under board flex conditions. The device supports a continuous current of 2 A and is intended for EMI filtering in sensitive electronic circuits.

Feature Summary

• Three-terminal feed-through architecture providing effective electromagnetic interference suppression
• FlexiCap flexible end termination system integrated with nickel barrier layers
• High current handling capability suitable for power line filtering applications

Applications

• Electromagnetic interference filtering in automotive electronics
• Power supply input stages requiring high current bypassing
• Board-flex sensitive circuit designs demanding enhanced mechanical stability

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal composition and dielectric characteristics. Ensure that the selected variant matches the required current rating and voltage derating guidelines for the target application environment. Cross-reference the package dimensions with PCB footprint libraries to guarantee accurate placement during assembly processes.

Selection Notes

Select this component when both EMI suppression and mechanical robustness are critical requirements. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Consider the FlexiCap feature for assemblies subject to thermal cycling or mechanical stress. Validate that the 50V DC rating aligns with the operational voltage headroom needed for reliable long-term performance.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in MLCCs with compliant terminations. The series addresses reliability issues associated with rigid terminations in modern thin-profile PCB designs. The 1806Y prefix indicates a three-terminal feed-through configuration within the 1806 case size family, distinct from standard parallel plate capacitors.

Replacement Considerations

Direct substitutes must match the three-terminal feed-through topology and 1806 dimensions. Verify compatibility of the nickel barrier termination process if solderability constraints exist. Standard two-terminal capacitors cannot replace this component due to differing impedance characteristics and mounting requirements.
