1806Y0500272MJTE07

Overview

The Knowles Syfer 1806Y0500272MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features an X7R dielectric with a capacitance of 2.7 nF and a tolerance of ±20%. The component is rated for a DC voltage of 50V and operates within a temperature range of -55°C to +125°C. It utilizes a FlexiCap termination system with a nickel barrier, housed in a standard 1806 (4516 metric) package.

Feature Summary

• Three-terminal architecture provides enhanced high-frequency noise suppression compared to standard two-terminal capacitors.
• FlexiCap termination technology incorporates a soft inner layer to improve mechanical reliability during thermal cycling and board flexing.
• Nickel barrier plating ensures robust solderability and corrosion resistance for surface mount assembly.

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF circuit noise attenuation

Procurement Notes

Verify the specific suffix TE07 against official datasheets to confirm the reel packaging configuration and terminal finish specifications. Ensure compatibility with automated pick-and-place equipment regarding the 1806 footprint dimensions. Confirm RoHS compliance status through current manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when superior high-frequency performance is required over standard MLCCs due to its internal ground plane structure. The X7R dielectric offers stable capacitance characteristics across the specified operating temperature range. Consider the FlexiCap feature if the application involves significant mechanical stress or thermal expansion mismatches between the component and the PCB substrate.

Part Context

This part belongs to the Knowles Syfer FlexiCap series of EMI filters. These components integrate capacitor functionality with shielding properties inherent to the three-terminal design. The series targets applications demanding compact solutions for electromagnetic interference mitigation in dense electronic layouts.

Replacement Considerations

Cross-reference with other 1806 package three-terminal EMI filters from Knowles Syfer or compatible manufacturers. Verify that substitute parts maintain identical capacitance, voltage rating, and termination flexibility to ensure mechanical and electrical equivalence.
