1806J1000393MXTE07

Overview

The Knowles Syfer 1806J1000393MXTE07 is a multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features a 1806 surface mount package with dimensions of 4.5 mm by 1.6 mm. The component provides a capacitance of 39 nF with a tolerance of ±20%. It utilizes X7R dielectric material and supports a DC voltage rating of 100 VDC. The device operates within a temperature range of -55°C to +125°C and incorporates nickel barrier terminations with 100% tin plating for reliable soldering.

Feature Summary

• Three-terminal architecture providing enhanced high-frequency noise suppression compared to standard two-terminal capacitors
• X7R dielectric composition ensuring stable capacitance performance across the specified operating temperature range
• Integrated EMI filtering capability suitable for sensitive electronic circuit protection

Applications

• High-frequency noise suppression in electronic circuits
• EMI filtering for signal lines requiring compact footprint solutions
• Power supply decoupling where common-mode noise reduction is critical

Procurement Notes

Verify the specific suffix TE07 against official manufacturer documentation to confirm termination plating and packaging details. Ensure the X7R dielectric type aligns with your thermal requirements, as it differs from C0G/NP0 variants. Confirm that the 1806 package dimensions fit your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, three-terminal EMI filter is required for 100V applications. The X7R dielectric offers higher volumetric efficiency than Class 1 alternatives but exhibits greater capacitance variation with temperature. Evaluate the ±20% tolerance against circuit sensitivity requirements to ensure adequate performance margins under varying conditions.

Part Context

This part belongs to the Knowles Syfer J-series of general-purpose MLCCs. It represents a specialized variant combining standard capacitor functionality with integrated EMI filtering through its three-terminal design. The 1806 case size balances current handling capabilities with space-saving requirements for modern surface-mount assembly processes.
