1806Y0500683MXTE01

Overview

The Knowles Syfer 1806Y0500683MXTE01 is a surface-mount multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features an 1806 (4516 metric) case size with a capacitance of 68.00 nF and a DC voltage rating of 50V. The component utilizes X7R dielectric material with a tolerance of ±20%. It incorporates FlexiCap technology with a nickel barrier for enhanced mechanical reliability. The rated current is 300 mA, and it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal architecture providing effective electromagnetic interference filtering
• FlexiCap construction with nickel barrier to mitigate board flex stress
• X7R dielectric composition ensuring stable performance across operating temperatures

Applications

• Electromagnetic interference suppression in sensitive electronic circuits
• Power supply input/output filtering applications
• Board-flex sensitive surface mount assemblies

Procurement Notes

Verify the specific suffix 'TE01' against official datasheets to confirm terminal configuration and packaging details. Ensure compatibility with RoHS directives if required by the target application. Cross-reference the manufacturer part number with authorized distributor listings to confirm current availability status and authenticity before procurement.

Selection Notes

Select this component when high capacitance density is required in an 1806 footprint alongside EMI filtering capabilities. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Consider the FlexiCap feature if the assembly process involves significant PCB bending or if the end-use environment subjects the board to mechanical stress.

Part Context

This component belongs to the Knowles Syfer MLCC portfolio, specifically engineered for robust surface-mount applications. The 1806Y series indicates a standard 1806 case dimension with Y-denoting specific electrical characteristics. As a specialized EMI filter capacitor, it integrates passive filtering directly into the power distribution network, reducing the need for additional discrete filter components.

Replacement Considerations
