1806Y2000682MJTE07

Overview

The Knowles Syfer 1806Y2000682MJTE07 is a multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features an X7R dielectric material with a capacitance of 6.8 nF and a tolerance of ±20%. The component is rated for a DC voltage of 200V and utilizes a FlexiCap termination structure incorporating a nickel barrier. This three-terminal configuration functions as an EMI filter, providing enhanced mechanical reliability against board bending and thermal cycling.

Feature Summary

• Three-terminal architecture integrated into the MLCC body to function as an effective EMI filter
• FlexiCap termination system utilizing proprietary flexible materials to withstand significant PCB flexing
• Nickel barrier layer incorporated within the termination structure for improved durability
• X7R dielectric composition ensuring stable electrical performance across a wide temperature range

Applications

• High-reliability electronic assemblies requiring robust EMI suppression
• Applications involving printed circuit boards subject to mechanical stress or bending
• Thermal cycling environments demanding superior crack resistance in ceramic components
• Space-qualified or high-performance industrial systems requiring verified termination integrity

Procurement Notes

Verify the specific package dimensions and termination compatibility during integration. Confirm that the three-terminal EMI filter topology aligns with the schematic design requirements. Ensure the 200V DC rating meets the operational voltage constraints of the target circuit. Check for any specific handling instructions related to the FlexiCap flexible terminations during assembly.

Selection Notes

Select this component when standard two-terminal MLCCs are insufficient due to mechanical stress or EMI requirements. The three-terminal design offers superior filtering compared to conventional capacitors. The FlexiCap feature is critical for applications where PCB warping or vibration is present. Verify that the 1806 footprint matches the available board space and pad layout.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in MLCCs with flexible terminations. These components are engineered to overcome the brittleness issues associated with traditional ceramic capacitors. The series has been qualified for demanding environments, including space applications, highlighting its reliability. The 1806Y series specifically addresses high-voltage needs within this flexible termination framework.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 6.8nF capacitance, 200V rating, and three-terminal EMI filter structure. Standard two-terminal replacements will not provide the same EMI filtering or mechanical flexibility. Verify that alternative FlexiCap parts maintain the nickel barrier construction for equivalent durability.

FAQ

What is the primary advantage of the three-terminal design in this capacitor?

The three-terminal design integrates an EMI filter directly into the capacitor, offering superior high-frequency noise suppression compared to standard two-terminal MLCCs.

How does the FlexiCap termination improve reliability?

The FlexiCap termination uses a proprietary flexible material that accommodates greater degrees of PCB bending and thermal cycling without cracking, significantly enhancing mechanical performance.

Is this component suitable for high-vibration environments?

Yes, the combination of the FlexiCap termination and nickel barrier provides increased tolerance to mechanical stress and vibration, making it suitable for demanding applications.
