Overview
The Knowles Syfer 1806J2000392MJTE07 is a multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features an 1806 (4516 metric) case size with a capacitance of 3.9 nF and a DC voltage rating of 200 VDC. The component utilizes X7R dielectric material, providing a tolerance of +/-20%. It is constructed as a three-terminal EMI filter with nickel barrier and 100% tin terminations, suitable for high-frequency noise suppression applications.
Feature Summary
- Three-terminal architecture for enhanced electromagnetic interference filtering
- X7R dielectric stability across operating temperature ranges
- Nickel barrier termination system for reliable soldering
Applications
- High-frequency noise suppression in electronic circuits
- Electromagnetic interference filtering for signal lines
- Power supply decoupling in compact SMD designs
Procurement Notes
Verify the specific suffix TE07 against official datasheets to confirm termination plating and packaging details. Ensure compatibility with automated pick-and-place equipment regarding the 1806 footprint. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and authenticity before procurement.
Selection Notes
Select this component when a compact 1806 footprint is required for EMI filtering at 200V DC. The X7R dielectric offers higher capacitance density than Class 1 materials but with lower stability. Consider the three-terminal design for superior high-frequency performance compared to standard two-terminal capacitors in similar packages.
Part Context
This part belongs to the Knowles Syfer MLCC family, specifically engineered for surface mount applications. It integrates passive filtering capabilities within a standard chip capacitor form factor, allowing designers to save board space by combining decoupling and filtering functions in a single component.
Replacement Considerations
Check for direct substitutes from the same series with identical terminal configurations. Verify that any replacement maintains the 1806 dimensions and 200V rating. Ensure the alternative component supports the required X7R characteristics and EMI filtering topology.
