1206Y2000272MSTE03

Overview

The Knowles Syfer 1206Y2000272MSTE03 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 2700 pF with a voltage rating of 200 V and a maximum current handling capacity of 50 mA. The component utilizes an X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates FlexiCap technology with a nickel barrier to enhance mechanical reliability under board flex conditions.

Feature Summary

• Integrated feed-through architecture provides effective electromagnetic interference filtering within a compact footprint.
• FlexiCap construction with nickel barrier improves resistance to mechanical stress and board flexing.
• X7R dielectric ensures consistent capacitance stability over the specified operating temperature range.

Applications

• High-frequency noise suppression in automotive electronic modules
• Signal line filtering in board-flex sensitive environments
• Power distribution network decoupling in compact PCB layouts

Procurement Notes

Verify the exact suffix MSTE03 against official Knowles Syfer documentation to confirm the specific termination and packaging configuration. Ensure compatibility with AEC-Q200 requirements if used in automotive applications. Confirm availability through authorized distributors as supply status may vary.

Selection Notes

Select this component when a feed-through topology is required for superior high-frequency attenuation compared to standard MLCCs. The 200V rating and 50mA current limit define the operational boundaries. Consider the 1206 size constraint and FlexiCap benefits for mechanical robustness in dynamic assemblies.

Part Context

This part belongs to the Knowles Syfer 1206Y series, which specializes in high-reliability multilayer ceramic capacitors. The Y-series designation typically indicates X7R dielectric characteristics. The inclusion of FlexiCap technology distinguishes these components from standard general-purpose MLCCs by offering enhanced durability in mechanically demanding applications.

Replacement Considerations

Direct substitutes must match the 1206 feed-through form factor, 2700pF capacitance, and 200V rating. Verify that alternative parts support the same 50mA current handling and offer comparable FlexiCap or equivalent mechanical flexibility features for board flex sensitivity.
