1806Y1000104MXTE01

Overview

The Knowles Syfer 1806Y1000104MXTE01 is a surface-mount feed-through capacitor designed for EMI suppression. It features a capacitance of 0.1 µF with a DC voltage rating of 100 VDC and X7R dielectric material. The component utilizes a three-terminal architecture within an 1806 (4516 metric) package, measuring 4.5 mm in length, 1.6 mm in width, and 1.3 mm in height. It includes a nickel barrier termination and supports a maximum current of 300 mA. The device operates reliably across a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal feed-through architecture provides enhanced high-frequency noise attenuation compared to standard two-terminal capacitors.
• Nickel barrier termination structure ensures robust solderability and long-term reliability under thermal stress.
• Flexible soft termination design accommodates board bending and mechanical strain, reducing the risk of cracking during assembly or operation.

Applications

• High-density electronic assemblies requiring effective electromagnetic interference filtering
• Power supply input stages for decoupling and noise suppression
• Signal lines sensitive to high-frequency transient disturbances

Procurement Notes

Verify the complete part number including the suffix to confirm specific termination and packaging configurations. Ensure compatibility with existing PCB footprint dimensions, particularly regarding the three-pad layout required for feed-through functionality. Confirm that the selected variant meets all necessary environmental and qualification standards for the intended deployment environment.

Selection Notes

Select this component when superior high-frequency performance is required over standard MLCCs. The three-terminal design offers lower parasitic inductance, making it suitable for critical noise-sensitive circuits. Evaluate the trade-off between the increased footprint size and the improved filtering efficiency to determine suitability for space-constrained designs.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which integrates flexible terminations to improve mechanical durability. The series is engineered for applications where standard rigid-termination capacitors might fail due to board flexure or thermal cycling stresses. The feed-through variant specifically targets EMI suppression needs in compact form factors.

Replacement Considerations

Direct substitutes must match the 1806 package, 100V rating, 0.1 µF capacitance, and three-terminal feed-through configuration. Verify that any alternative component maintains equivalent electrical characteristics and physical dimensions to ensure seamless integration without PCB redesign.
