1206Y2000122MSTE03

Overview

The Knowles Syfer 1206Y2000122MSTE03 is a three-terminal feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 1200 pF with a voltage rating of 200 VDC and a current rating of 50 mA. The component utilizes an X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) surface-mount package, it offers low impedance characteristics suitable for EMI filtering applications.

Feature Summary

• Three-terminal feed-through architecture for enhanced high-frequency noise attenuation
• X7R dielectric construction ensuring reliable operation within specified thermal limits
• Integrated nickel barrier structure for robust solderability and mechanical stability

Applications

• EMI/RFI filtering in automotive electronic control units
• Noise suppression in high-speed digital signal lines
• Power distribution network decoupling in sensitive RF circuits

Procurement Notes

Verify the specific suffix STE03 against official datasheets to confirm the presence of the nickel barrier and terminal configuration. Ensure compatibility with PCB pad layouts designed for three-terminal components. Confirm AEC-Q200 qualification status if required for automotive-grade reliability standards before finalizing procurement.

Selection Notes

Select this component when superior high-frequency attenuation is required compared to standard two-terminal MLCCs. The three-terminal design provides lower parasitic inductance, making it ideal for suppressing broadband noise. Consider the 50 mA current rating and 200 VDC voltage limit to ensure adequate headroom for the target circuit environment.
