1806Y2000683MJTE07

Overview

The Knowles Syfer 1806Y2000683MJTE07 is a three-terminal EMI filter capacitor in an 1806 (4516 metric) surface-mount package. It features a capacitance of 0.068 µF with a ±20% tolerance and utilizes X7R dielectric material. The component is rated for 200 VDC and incorporates a FlexiCap design with a nickel barrier to enhance mechanical reliability. This configuration provides effective electromagnetic interference suppression while maintaining structural integrity under board flex conditions.

Feature Summary

• Three-terminal architecture designed for superior high-frequency noise attenuation compared to standard two-terminal capacitors
• FlexiCap technology with nickel barrier construction to mitigate stress-induced cracking during PCB flexing or thermal cycling
• X7R ceramic dielectric providing stable capacitance characteristics across a wide operating temperature range

Applications

• Electromagnetic interference filtering in automotive electronic control units
• Noise suppression in board-flex sensitive industrial equipment
• Power supply input/output decoupling in compact consumer electronics

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal configuration and termination plating specifications. Ensure that the selected variant matches the required voltage rating and capacitance tolerance for the target circuit design. Cross-reference the package dimensions with the approved footprint library to guarantee proper solder joint formation and mechanical stability during assembly processes.

Selection Notes

Select this component when high-frequency noise suppression is critical within space-constrained designs requiring enhanced mechanical durability. The three-terminal structure offers better performance than standard MLCCs in EMI-sensitive applications. Evaluate the X7R dielectric properties against the operational temperature profile to ensure capacitance stability meets system requirements under varying thermal conditions.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in robust multilayer ceramic capacitors engineered for demanding environments. The series addresses common failure modes associated with mechanical stress in surface-mount devices. The 1806 form factor balances current handling capabilities with compact board real estate, making it suitable for dense modern electronic assemblies.

Replacement Considerations

Direct substitutes include other 1806 three-terminal EMI filters from the same manufacturer family with matching electrical ratings. Verify that any alternative maintains the three-terminal topology and nickel barrier construction to preserve mechanical reliability standards.
