1806J0500184MXTE07

Overview

The Knowles Syfer 1806J0500184MXTE07 is a surface-mount feed-through capacitor designed for EMI suppression. It features a capacitance of 0.18 µF with a ±20% tolerance and an X7R dielectric. The component is rated for 50 VDC and supports a continuous current of 2 A. It utilizes a 1806 (4516 metric) package size with three terminals, including a center pin for direct mounting to ground planes. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Three-terminal feed-through architecture enables low-inductance grounding via the center pin.
• X7R ceramic dielectric provides stable capacitance characteristics across the specified temperature range.
• High continuous current rating of 2 A supports power line filtering applications.

Applications

• EMI suppression on DC power input lines
• Signal filtering in high-noise industrial environments
• Ground plane integration for low-impedance return paths

Procurement Notes

Verify the specific termination finish and RoHS compliance status against the latest manufacturer datasheet before procurement. Confirm that the 1806 footprint dimensions align with the PCB layout constraints. Ensure the selected packaging format matches the assembly equipment requirements. Cross-reference the part number suffix to confirm the exact terminal configuration and material specifications.

Selection Notes

Select this component when a compact, high-current EMI filter is required for 50V DC circuits. The 1806 package offers a balance between capacitance value and board space. Consider the X7R temperature coefficient if the application operates within the -55°C to +125°C range. Evaluate the 2A current rating against the maximum expected load current to ensure reliable operation without thermal degradation.

Part Context

This part belongs to the Knowles Syfer Syfer Power series of surface-mount feed-through capacitors. These components are engineered to replace traditional discrete inductor-capacitor networks in a single compact package. The 1806J series specifically targets applications requiring robust EMI performance in limited spaces, leveraging the three-terminal design for superior high-frequency attenuation compared to standard two-terminal MLCCs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative manufacturers by matching the 1806 footprint, 0.18 µF capacitance, 50V rating, and three-terminal feed-through structure.
