Overview
The Knowles Syfer 1206Y2000473MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed as a three-terminal EMI filter. It features a capacitance of 47 nF with a tolerance of ±20%, rated for a DC voltage of 200 V, and utilizes an X7R dielectric material. The component operates within a temperature range of -55°C to +125°C and is housed in a standard 1206 (3216 metric) package. It incorporates FlexiCap technology with a nickel barrier and tin termination to enhance mechanical reliability.
Feature Summary
- Three-terminal architecture provides effective electromagnetic interference filtering for high-frequency noise suppression.
- FlexiCap construction with flexible terminations reduces stress on the substrate during board flexing events.
- Nickel barrier plating ensures robust solderability and long-term corrosion resistance.
Applications
- High-speed digital signal line protection
- Power supply input/output filtering
- RF circuit noise attenuation
Procurement Notes
Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination and packaging specifications. Confirm RoHS compliance status and specific datasheet revisions prior to procurement. Cross-reference distributor listings with the original manufacturer's catalog to validate authenticity and technical accuracy.
Selection Notes
Select this component when board flex sensitivity is a concern due to its flexible termination design. Ensure the operating voltage does not exceed the 200 VDC rating and that the required capacitance stability aligns with X7R characteristics. Verify footprint compatibility with the 1206 package dimensions during layout.
Part Context

FAQ
What is the primary function of the three-terminal design?
The three-terminal design functions as an EMI filter, providing superior high-frequency noise attenuation by grounding the center terminal.
How does FlexiCap technology benefit the component?
FlexiCap technology uses flexible terminations to absorb mechanical stress, preventing cracks in the ceramic body during PCB flexing or thermal cycling.
