1806J1000821MCTE01

Overview

The Knowles Syfer 1806J1000821MCTE01 is a three-terminal feed-through capacitor designed for surface mount applications. It features an 820 pF capacitance with a 100 VDC voltage rating and operates within a temperature range of -55°C to +125°C. The component utilizes a C0G dielectric material housed in a compact 1806 (4516 metric) package. It provides a maximum DC resistance of 0.35 Ω and supports a current rating of 0.3 A, ensuring stable performance in high-frequency filtering environments.

Feature Summary

• Three-terminal EMI filter architecture for enhanced noise suppression
• Feed-through design integrating ground plane functionality
• C0G dielectric ensures minimal capacitance variation over temperature

Applications

• High-frequency signal line filtering
• Power supply decoupling in sensitive circuits
• EMI suppression in communication modules

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm terminal plating and barrier layer specifications. Ensure compatibility with standard 1806 footprints during layout. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when space-constrained EMI filtering is required without sacrificing current handling capabilities. The three-terminal structure offers superior high-frequency performance compared to standard two-terminal capacitors. Evaluate thermal management requirements given the 0.35 Ω internal resistance under load conditions.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which specializes in compact EMI solutions. These components are engineered for robustness in demanding electronic environments, combining low parasitic inductance with high current tolerance. The 1806 form factor allows for dense PCB layouts while maintaining effective noise attenuation characteristics.

Replacement Considerations

Consult official substitution guides for equivalent three-terminal feed-through capacitors from the same manufacturer family. Verify that alternative parts match the 820 pF capacitance, 100 VDC rating, and 1806 package dimensions to ensure mechanical and electrical compatibility.
