1806Y2000333MJTE07

Overview

The Knowles Syfer 1806Y2000333MJTE07 is a Class 1 multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a 1806 (4516 metric) case size with a capacitance of 0.033 µF and a DC voltage rating of 200 V. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across varying conditions. It offers a tolerance of ±20% and is rated for operation within a temperature range of -55°C to +125°C. This feed-through capacitor integrates a 2 A current rating, combining filtering capabilities with high reliability in a compact form factor suitable for dense PCB layouts.

Feature Summary

• Integrates feed-through functionality for effective noise suppression in signal lines
• Utilizes C0G/NP0 dielectric for minimal capacitance variation over temperature and voltage
• Supports high continuous current handling up to 2 A within the capacitor structure
• Constructed with flexible terminations to enhance mechanical durability on flexible substrates

Applications

• High-frequency signal filtering in communication equipment
• Power supply input stages requiring combined decoupling and current carrying capacity
• Automotive electronics systems demanding high reliability and thermal stability
• Industrial control circuits sensitive to electromagnetic interference

Procurement Notes

Verify the specific termination configuration and lead style against the official datasheet before integration, as feed-through variants may differ from standard MLCC footprints. Confirm RoHS compliance status and environmental declarations directly from the manufacturer's documentation. Ensure that the PCB pad layout accommodates the unique internal structure of the feed-through design to maintain electrical integrity and mechanical strength during assembly processes.

Selection Notes

Select this component when both signal filtering and moderate current carrying capability are required in a single surface-mount device. The C0G dielectric ensures precision for timing or coupling applications where capacitance drift is unacceptable. Consider the 1806 package dimensions for space-constrained designs. Evaluate the 200V rating against peak transient voltages in the circuit to ensure adequate safety margins under all operating conditions.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors with flexible terminations for use on flex circuits and rigid-flex boards. The 1806Y series designation indicates a Class 1 ceramic construction optimized for high-frequency stability. As a feed-through type, it differs from standard two-terminal MLCCs by providing a direct conductive path through the center, offering superior high-frequency attenuation characteristics compared to conventional parallel-plate structures.

Replacement Considerations

Direct substitutes must match the 1806 feed-through form factor, 0.033 µF value, 200V rating, and C0G dielectric. Verify that alternative parts support the same 2 A current rating and compatible termination flexibility if used on flex substrates. Cross-reference pinout and dimensional drawings to ensure PCB footprint compatibility without redesign.
