1806J0500184MJTE07

Overview

The Knowles Syfer 1806J0500184MJTE07 is a surface-mount feed-through capacitor designed for EMI suppression. It features a capacitance of 0.18 µF with a tolerance of ±20%. The component operates at a DC voltage rating of 50V and supports a continuous current of 2A. It utilizes an X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. The device is housed in a standard 1806 (4.5mm x 1.6mm) package with a maximum height of 1.3mm.

Feature Summary

• Three-terminal feed-through architecture for effective common-mode noise attenuation
• High current handling capability suitable for power line filtering applications
• X7R ceramic dielectric ensures reliable capacitance stability over wide temperature variations

Applications

• EMI suppression in DC power input circuits
• Noise filtering for automotive electronic modules
• Signal integrity protection in industrial control systems

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm termination finish and packaging type. Ensure the selected variant matches the required current rating and capacitance tolerance for the target circuit design. Cross-reference the Mouser or DigiKey part numbers to validate availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when high-current EMI filtering is required in a compact surface-mount footprint. The 1806 case size offers a balance between thermal performance and board space efficiency. Consider the 2A current rating and 50V voltage limit to ensure adequate derating margins for the specific application environment.

Part Context

This component belongs to the Knowles Syfer SyferTech series of multilayer ceramic capacitors. The brand specializes in application-specific passive components for demanding environments. The 1806J series specifically targets EMI suppression needs where traditional two-terminal capacitors may be insufficient due to parasitic inductance limitations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative three-terminal feed-through capacitors by matching the 1806 package dimensions, 0.18 µF capacitance, and 50V/2A ratings.
