1806J1000392MXTE01

Overview

The Knowles Syfer 1806J1000392MXTE01 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 3900 pF with a tolerance of ±20% and a DC voltage rating of 100 VDC. The component utilizes C0G (NP0) dielectric material to ensure stable performance across varying conditions. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 4.5 mm in length, 1.6 mm in width, and 1.3 mm in height, conforming to the 1806 (4516 metric) package size.

Feature Summary

• Three-terminal feed-through architecture provides effective electromagnetic interference filtering.
• C0G/NP0 dielectric ensures minimal capacitance variation over temperature and voltage changes.
• FlexiCap™ construction enhances mechanical reliability and resistance to board flexure stress.

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive analog circuits
• EMI suppression in automotive electronic control units

Procurement Notes

Verify the specific suffix 'E01' against official datasheets to confirm terminal configuration and termination plating specifications. Ensure compatibility with automated pick-and-place equipment regarding the 1806 package footprint. Confirm RoHS compliance status through current manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when compact EMI filtering is required on high-speed lines without significant impedance mismatch. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Consider the 100V rating and 3900pF value for applications requiring moderate capacitance with strict stability requirements under thermal cycling.

Part Context

This part belongs to the Knowles Syfer FlexiCap™ series, which specializes in robust multilayer ceramic structures. The 1806J series denotes a specific form factor optimized for surface-mount assembly. As a feed-through capacitor, it integrates filtering functionality directly into the circuit path, reducing the need for additional discrete components.
