Overview
The Knowles Syfer 1806J1000390MCTE01 is a three-terminal EMI filter capacitor designed for surface-mount applications. It features a 39 pF capacitance with a ±20% tolerance and a 100 VDC voltage rating. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a compact 1806 (4516 metric) package measuring 4.5 mm x 1.6 mm x 1.1 mm, it provides effective high-frequency noise suppression.
Feature Summary
- Three-terminal architecture for enhanced electromagnetic interference filtering
- C0G (NP0) dielectric for consistent capacitance stability over temperature variations
- Compact 1806 surface-mount footprint for dense circuit board layouts
Applications
- High-frequency noise suppression in sensitive electronic circuits
- EMI filtering in communication equipment signal lines
- Power supply decoupling in automotive electronics
Procurement Notes
Verify the specific suffix configuration against official datasheets to confirm terminal arrangement and termination plating specifications. Ensure compatibility with automated pick-and-place equipment regarding the 1806 package dimensions. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.
Selection Notes
Select this component when superior high-frequency attenuation is required compared to standard two-terminal capacitors. The three-terminal design offers lower parasitic inductance, making it suitable for RF and high-speed digital applications. Evaluate thermal management requirements within the specified -55°C to +125°C operational range during system design.
Part Context
This part belongs to the Knowles Syfer E01 series of feed-through capacitors. These components are engineered specifically for EMI suppression rather than general energy storage. The three-terminal structure differentiates them from standard MLCCs by providing a grounded center electrode for improved filtering efficiency.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify pinout compatibility and electrical characteristics before considering alternative manufacturers.
