1806J0500473MXTE07

Overview

The Knowles Syfer 1806J0500473MXTE07 is a three-terminal EMI filter capacitor in an 1806 (4516 metric) surface-mount package. It features a 0.047 µF capacitance with ±20% tolerance and a 50 VDC rated voltage. The component utilizes X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Designed for high-frequency noise suppression, it incorporates a nickel barrier termination system with 100% tin plating to facilitate reliable soldering and long-term environmental stability.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering compared to standard two-terminal capacitors
• Nickel barrier termination structure ensures robust solderability and resistance to corrosion
• X7R ceramic dielectric maintains consistent capacitance characteristics over wide industrial temperature variations

Applications

• High-speed digital signal line filtering in communication equipment
• Power supply input/output decoupling in compact electronic modules
• EMI suppression in automotive infotainment and control systems

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and dielectric specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production workflows. Cross-reference datasheet revisions to validate current manufacturing parameters.

Selection Notes

Select this component when space-constrained designs require superior high-frequency attenuation in a standard 1806 footprint. The three-terminal design offers better parasitic inductance reduction than conventional MLCCs. Ensure circuit operating voltages remain within the 50 VDC limit and temperatures stay within the specified industrial range for optimal reliability.

Part Context

This component belongs to the Knowles Syfer EMI filter series, specialized for surface-mount applications requiring effective noise suppression. The 1806 case size balances physical footprint with electrical performance, making it suitable for dense PCB layouts where standard capacitors may not provide adequate high-frequency isolation.

Replacement Considerations

Direct substitutes include other 1806 three-terminal EMI filters from the same manufacturer family, such as variants with different capacitance values or voltage ratings. Verify that alternative components maintain compatible termination materials and mounting dimensions to ensure mechanical interchangeability.
