1806Y1000473MXTE01

Overview

The Knowles Syfer 1806Y1000473MXTE01 is a three-terminal feed-through multilayer ceramic capacitor designed for surface-mount technology. It features an X7R dielectric with a capacitance of 47 nF and a DC voltage rating of 100 VDC. The component operates within a temperature range of -55°C to +125°C and exhibits a tolerance of ±20%. Housed in an 1806 (4516 metric) package, it provides effective electromagnetic interference filtering through its integrated ground terminal structure.

Feature Summary

• Three-terminal feed-through architecture for enhanced high-frequency noise suppression
• X7R dielectric material ensuring stable capacitance across wide temperature variations
• Integrated ground connection minimizing parasitic inductance in EMI filter applications

Applications

• High-density PCB layouts requiring compact EMI filtering solutions
• Power supply input stages for noise attenuation
• Signal line protection in sensitive electronic circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required termination materials and packaging formats. Confirm that the X7R dielectric characteristics align with the thermal profile of the target application environment. Cross-reference the 1806 footprint dimensions with the design layout to guarantee proper solder joint formation and mechanical stability during assembly processes.

Selection Notes

Select this component when space constraints necessitate a small form factor combined with robust EMI performance. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Ensure the 100V DC rating exceeds the maximum circuit voltage including transients. Consider the X7R temperature coefficient if operating conditions involve significant thermal fluctuations.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which utilizes a unique internal structure to integrate the ground plane directly into the component body. This design reduces loop inductance significantly, making it ideal for suppressing common-mode noise in modern high-speed digital and power electronics where traditional discrete filters are too large or ineffective.
