1806J1000473MXTE07

Overview

The Knowles Syfer 1806J1000473MXTE07 is a three-terminal EMI filter capacitor in an 1806 (4516 metric) surface-mount package. It features a capacitance of 47 nF with a ±20% tolerance and a DC voltage rating of 100 V. The dielectric material is X7R (2R1), providing stability across a temperature range of -55°C to +125°C. Terminal finishes consist of nickel barrier and 100% tin plating.

Feature Summary

• Three-terminal architecture designed for effective electromagnetic interference suppression
• X7R dielectric composition ensures reliable performance within specified thermal limits
• Nickel barrier and tin terminal finish supports standard surface-mount reflow processes

Applications

• Electromagnetic interference filtering in electronic circuits
• Power supply input/output noise reduction
• Signal line protection in high-reliability systems

Procurement Notes

Verify the specific suffix TE07 against official manufacturer documentation to confirm terminal configuration and packaging details. Ensure compatibility with X7R dielectric characteristics for your operating temperature range. Cross-reference the 1806 footprint dimensions with your PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a 47 nF capacitance value is required at 100 VDC with moderate tolerance. The X7R dielectric offers higher volumetric efficiency than C0G types but exhibits greater capacitance variation with temperature. Confirm that the three-terminal EMI filter topology meets the circuit's noise attenuation needs compared to standard two-terminal capacitors.

Part Context

This part belongs to the Knowles Syfer multilayer ceramic capacitor family, specifically categorized as an EMI suppression filter. The 1806J series designation indicates the case size and voltage class. These components are engineered for surface-mount assembly in compact electronic designs requiring robust noise filtering capabilities.
