1206Y2000273MSTE03

Overview

The Knowles Syfer 1206Y2000273MSTE03 is a feed-through capacitor in a 1206 (3216 metric) surface-mount package. It features a capacitance of 0.027 µF with a rated DC voltage of 200V and a maximum current rating of 50 mA. The component utilizes X7R dielectric technology and incorporates FlexiCap™ nickel barrier construction for enhanced mechanical reliability.

Feature Summary

• Integrated feed-through design providing EMI filtering within the capacitor structure
• FlexiCap™ nickel barrier end termination to improve board flex resistance
• X7R temperature coefficient ceramic dielectric for stable performance

Applications

• Automotive electronics requiring AEC-Q200 qualification
• Circuits sensitive to board flex deformation
• EMI suppression in compact surface-mount layouts

Procurement Notes

Verify the specific suffix MSTE03 against official Knowles Syfer documentation to confirm the FlexiCap™ nickel barrier configuration. Ensure the selected variant meets the required 50 mA current rating and 200V DC withstand specifications for the target application environment.

Selection Notes

Select this component when both high-frequency noise attenuation and mechanical robustness are critical. The integrated feed-through topology reduces footprint compared to discrete filter components. Confirm that the 1206 package dimensions align with the PCB land pattern and that the 50 mA current limit satisfies the circuit's operational requirements.

Part Context

This part belongs to the Knowles Syfer 1206Y series, which specializes in high-reliability MLCCs. The series integrates filtering capabilities directly into the capacitor body, offering a compact solution for electromagnetic interference management in space-constrained electronic assemblies.
