1806Y1000222MJTE07

Overview

The Knowles Syfer 1806Y1000222MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for general-purpose applications. It features a 1806 (4520 metric) case size with a nominal capacitance of 2.2 nF and a DC voltage rating of 100 VDC. The component utilizes X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. It offers a tolerance of ±20% and employs standard SMD/SMT terminations for reliable board mounting.

Feature Summary

• Utilizes X7R dielectric material for stable capacitance characteristics over a wide operating temperature range.
• Features a compact 1806 surface-mount package suitable for high-density circuit board layouts.
• Designed with standard SMD/SMT terminations for automated assembly processes.

Applications

• General-purpose decoupling in electronic circuits
• Bypass filtering in power supply lines
• Signal coupling in general electronics

Procurement Notes

Verify the specific manufacturer designation, as sourcing data may list this part under Knowles Johanson Manufacturing or related entities due to corporate restructuring. Confirm that the ordering suffix matches the required termination and packaging specifications. Ensure compatibility with RoHS directives if applicable to your manufacturing standards before finalizing procurement orders.

Selection Notes

Select this component when a 1806 footprint is required for 100V applications needing moderate capacitance stability. The X7R dielectric provides a balance between cost and performance, making it suitable for non-critical timing or filtering tasks where tight tolerance is not mandatory. Consider thermal derating curves for operation near maximum temperature limits.

Part Context

This component belongs to the Knowles Syfer line of general-type MLCCs. It is distinct from high-reliability or specialized filter series within the same brand portfolio. The 1806Y prefix indicates the case size and dielectric type, while the suffix denotes specific terminal and packaging variations available through distributors.

Replacement Considerations

Direct substitutes must match the 1806 case size, 100V rating, 2.2nF value, and X7R dielectric. Verify that alternative manufacturers offer compatible footprint dimensions and termination plating to ensure mechanical fit and solderability without redesigning the PCB layout.
