1806J0250822MJTE07

Overview

The Knowles Syfer 1806J0250822MJTE07 is a three-terminal EMI filter capacitor in an 1806 (4516 metric) surface-mount package. It features a capacitance of 8200 pF with a ±20% tolerance and a DC voltage rating of 25 VDC. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Designed for high-reliability applications, it incorporates a nickel barrier termination system to enhance solderability and mechanical durability in SMD/SMT assembly processes.

Feature Summary

• Three-terminal architecture provides effective electromagnetic interference filtering
• Nickel barrier termination system ensures robust solderability and reliability
• X7R dielectric maintains stability across wide industrial temperature ranges

Applications

• High-frequency signal line noise suppression
• Power distribution network decoupling
• EMI filtering in sensitive electronic circuits

Procurement Notes

Verify the specific suffix JE07 against official datasheets to confirm terminal plating and packaging details. Ensure compatibility with automated pick-and-place equipment due to the 1806 footprint. Cross-reference RoHS compliance status directly with manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when compact EMI filtering is required in space-constrained designs. The three-terminal configuration offers superior high-frequency attenuation compared to standard two-terminal capacitors. Verify that the 25V rating aligns with circuit peak voltages and that the X7R characteristics suit the thermal environment.

Part Context

This part belongs to the Knowles Syfer high-reliability MLCC series, specifically designed for demanding environments. The 1806 case size balances capacitance density with physical footprint. As a specialized EMI filter, it differs from general-purpose capacitors by integrating ground terminals for enhanced noise dissipation.

FAQ

What is the primary function of the third terminal?

The third terminal serves as a dedicated ground connection, enabling effective shunting of common-mode noise currents away from sensitive signal lines.

How does the nickel barrier termination benefit the component?

The nickel barrier provides a reliable intermediate layer between the ceramic body and the outer tin plating, improving solder joint integrity and resistance to corrosion during reflow processes.
