1806Y1000392MXTE01

Overview

The Knowles Syfer 1806Y1000392MXTE01 is a three-terminal feed-through multilayer ceramic capacitor designed for surface mount applications. It features a 1806 (4516 metric) package with a capacitance of 3900 pF and a DC voltage rating of 100 VDC. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. This EMI filter provides high current handling capabilities up to 300 mA, making it suitable for noise suppression in sensitive electronic circuits.

Feature Summary

• Three-terminal feed-through architecture for effective electromagnetic interference filtering
• C0G/NP0 dielectric material providing stable capacitance characteristics over temperature variations
• High current carrying capacity suitable for power line noise suppression applications

Applications

• Electromagnetic interference filtering in communication equipment
• Noise suppression on power supply lines in industrial electronics
• EMI mitigation in aerospace and defense systems requiring high reliability

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm terminal configuration and termination material specifications. Ensure compatibility with PCB pad layouts designed for three-terminal feed-through components. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when high-frequency noise attenuation is required alongside significant current handling. The three-terminal design offers superior grounding paths compared to standard two-terminal capacitors. Evaluate thermal management requirements as the component dissipates energy during filtering operations within the specified temperature range.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, specialized for EMI/RFI suppression. These components integrate filtering functions directly into the circuit layout, reducing board space usage. The series is engineered for high-reliability environments where consistent electrical performance under mechanical stress is critical.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 3900 pF capacitance, 100 VDC rating, and three-terminal feed-through structure. Verify that alternative parts support the same 300 mA current rating and C0G dielectric stability. Cross-reference pinout configurations to ensure compatible mounting and grounding schemes.
