1806J2000223MXTE07

Overview

The Knowles Syfer 1806J2000223MXTE07 is a three-terminal multilayer ceramic capacitor (MLCC) designed for EMI filtering applications. It features an 1806 surface-mount package with X7R dielectric characteristics, providing stable capacitance across a wide temperature range. The component offers a nominal capacitance of 22 nF with a tolerance of ±20%, rated for a DC voltage of 200 V and a continuous current handling capacity of 2 A. It utilizes a nickel barrier electrode structure terminated with 100% tin plating to ensure reliable solderability and corrosion resistance in harsh environments.

Feature Summary

• Three-terminal architecture enables effective common-mode noise suppression and EMI filtering in compact layouts.
• Nickel barrier internal electrodes combined with 100% tin terminations provide robust mechanical strength and soldering reliability.
• X7R dielectric material ensures consistent capacitance performance over the specified industrial operating temperature range.

Applications

• High-frequency EMI filtering in power supply input stages
• Noise suppression in automotive electronic control units
• Signal integrity protection in industrial communication interfaces

Procurement Notes

Verify the complete part number including the suffix to confirm the specific termination and packaging configuration. Ensure compatibility with standard SMT reflow profiles and check for RoHS compliance documentation. Confirm that the 2 A current rating aligns with the thermal management capabilities of the target PCB design to prevent overheating during operation.

Selection Notes

Select this component when high-current EMI filtering is required in space-constrained designs. The 1806 footprint balances size and power handling. Consider the 200 VDC rating for safety margins in higher voltage circuits. Verify that the three-terminal layout fits the available PCB trace routing without causing short circuits between ground and signal lines.

Part Context

This component belongs to the Knowles Syfer XT series of high-reliability ceramic capacitors. The series is engineered for demanding applications requiring stable electrical performance under thermal and mechanical stress. The 1806 case size is a standard metric equivalent widely used in modern electronics manufacturing for balanced performance and assembly efficiency.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-referencing requires matching the 1806 footprint, 22 nF capacitance, 200 V rating, 2 A current capability, and three-terminal EMI filter topology from other manufacturers.
