1206Y1000223MSTE03

Overview

The Knowles Syfer 1206Y1000223MSTE03 is a feed-through multilayer ceramic capacitor in a 1206 (3216 metric) surface-mount package. It features an X7R dielectric with a nominal capacitance of 0.022 µF and a voltage rating of 100 VDC. The component offers ±20% tolerance and operates within a temperature range of -55°C to +125°C. It utilizes a FlexiCap nickel barrier termination system for enhanced mechanical reliability.

Feature Summary

• X2Y architecture providing integrated common-mode filtering capabilities
• FlexiCap nickel barrier terminations designed to withstand board flex stress
• Feed-through design enabling efficient high-frequency noise suppression

Applications

• Automotive electronics requiring AEC-Q200 qualification
• High-reliability industrial control systems
• Data communication interfaces needing EMI protection

Procurement Notes

Verify the specific suffix MSTE03 against official Knowles Syfer documentation to confirm the exact termination material and reel configuration. Ensure compatibility with automated pick-and-place equipment regarding the 1206 footprint dimensions. Confirm that the X7R dielectric characteristics meet the thermal stability requirements of the target application environment before finalizing procurement.

Selection Notes

Select this component when space-constrained designs require combined decoupling and filtering functions. The X2Y topology reduces the need for discrete components, simplifying the bill of materials. Consider the 100V rating and 0.022µF value for signal line protection. Evaluate the FlexiCap feature if the assembly process involves significant PCB bending or warping during soldering.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in robust MLCCs for demanding environments. The 1206Y series designation indicates a standard 1206 case size with specific internal build configurations. The MSTE03 suffix typically denotes specific packaging and terminal variations within the manufacturer's catalog structure.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 100V rating, 0.022µF capacitance, and X2Y feed-through topology. Verify that alternative components also offer FlexiCap or equivalent flexible terminations if board flex resistance is critical. Cross-reference AEC-Q200 certification if automotive compliance is required.
