1806Y2000472MJTE07

Overview

The Knowles Syfer 1806Y2000472MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for EMI filtering applications. It features a 1806 (4516 metric) package size with three terminals, functioning as a feed-through capacitor. The component has a capacitance of 4700 pF and a DC voltage rating of 200V. It utilizes an X7R dielectric material with a tolerance of +/-20%. The device operates within a temperature range of -55°C to +125°C and incorporates a nickel barrier termination structure.

Feature Summary

• Three-terminal feed-through architecture for effective electromagnetic interference suppression
• Nickel barrier termination technology for enhanced reliability
• X7R dielectric material providing stable capacitance characteristics

Applications

• Electromagnetic interference (EMI) filtering in electronic circuits
• Connector filtering applications
• Power supply line noise suppression

Procurement Notes

Verify the specific manufacturer designation, as some sources list this part under Knowles Johanson Manufacturing while others use Knowles Syfer. Confirm the package type is indeed the 1806 footprint and that the termination includes a nickel barrier. Ensure the voltage rating matches the 200V requirement for your circuit design before procurement.

Selection Notes

Select this component when a 3-terminal EMI filter is required in a 1806 SMD package. It is suitable for applications needing 4700 pF capacitance at 200V DC. Consider the nickel barrier termination if corrosion resistance or specific soldering profiles are required. Verify compatibility with automated placement equipment due to the small form factor.

Part Context

This component belongs to the Knowles Syfer MLCC series, specifically engineered for high-reliability environments. The 1806Y series typically denotes feed-through capacitors with specific terminal configurations. These parts are often used in aerospace, medical, and industrial sectors where robust EMI performance is critical.

Replacement Considerations

Check for direct substitutes from the same manufacturer family with identical pinout and electrical ratings. Ensure any replacement maintains the 3-terminal feed-through structure and nickel barrier termination to preserve EMI filtering efficacy and mechanical compatibility.
