Overview
The Knowles Syfer 1806J2000393MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features an X7R dielectric material and operates within a temperature range of -55°C to +125°C. The component provides a capacitance of 0.039 µF with a ±20% tolerance and a DC voltage rating of 200V. Housed in the standard 1806 (4516 metric) package, it utilizes nickel barrier terminations with 100% tin plating.
Feature Summary
- Utilizes X7R dielectric for stable capacitance across wide temperature variations
- Features nickel barrier termination structure with 100% tin plating for enhanced solderability
- Designed for high-reliability surface-mount integration
Applications
- High-reliability electronic circuits requiring stable capacitance
- General-purpose MLCC applications in harsh thermal environments
- Industrial equipment power conditioning
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm exact termination and packaging specifications. Ensure compatibility with existing PCB footprints and reflow profiles. Cross-reference datasheet parameters for voltage derating requirements under operating conditions.
Selection Notes
Select this component when a 200V rating and 0.039 µF value are required in an 1806 footprint. Consider the X7R characteristic for general coupling or decoupling where moderate temperature stability suffices. Evaluate the nickel barrier termination for lead-free assembly compliance and long-term reliability needs.
Part Context
This part belongs to the Knowles Syfer high-reliability MLCC portfolio. These components are engineered for demanding environments, offering robust performance compared to standard commercial grade capacitors. The series supports various capacitance values and voltage ratings within standardized EIA case sizes.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify that any substitute matches the 1806 dimensions, 200V rating, and X7R characteristics.
