1806J1000184MXTE01

Overview

The Knowles Syfer 1806J1000184MXTE01 is a three-terminal EMI filter capacitor in an 1806 (4516 metric) surface-mount package. It features a capacitance of 180 nF with a tolerance of ±20% and utilizes X7R dielectric material. The component has a DC voltage rating of 100 VDC and operates within a temperature range of -55°C to +125°C. Termination consists of nickel barrier with 100% tin plating, ensuring reliable solderability for high-frequency noise suppression applications.

Feature Summary

• Three-terminal architecture designed for effective electromagnetic interference filtering
• Utilizes X7R ceramic dielectric for stable capacitance characteristics across operating temperatures
• Nickel barrier termination with 100% tin plating for robust surface-mount reliability

Applications

• High-frequency noise suppression in electronic circuits
• Power supply input/output filtering stages
• Signal line protection against electromagnetic interference

Procurement Notes

Verify the specific suffix configuration against official manufacturer documentation to confirm terminal count and termination materials. Ensure the procurement channel provides valid traceability for the Knowles Syfer brand. Cross-reference the Mouser or DigiKey part numbers with the original datasheet to validate the X7R dielectric and 100V rating specifications before finalizing orders.

Selection Notes

Select this component when a compact 1806 footprint is required for EMI filtering with moderate capacitance values. The X7R dielectric offers higher volumetric efficiency compared to Class 1 ceramics, making it suitable for general-purpose decoupling and filtering where tight stability is not critical. Verify that the 100V rating meets the circuit's maximum DC bias requirements.

Part Context

This component belongs to the Knowles Syfer MLCC series, specifically engineered as a three-terminal EMI filter. The 1806 case size balances board space constraints with sufficient capacitance density. The product line targets industries requiring reliable passive components for noise reduction in sensitive analog and digital environments.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 180 nF capacitance, 100V rating, and three-terminal structure. Verify that alternative manufacturers offer compatible X7R dielectrics and similar termination plating to ensure mechanical and electrical interchangeability without redesigning the PCB layout.
