1206Y0500154MSTE03

Overview

The Knowles Syfer 1206Y0500154MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features an X7R dielectric with a capacitance of 150 nF and a voltage rating of 50 VDC. The component utilizes a 1206 (3216 metric) package size and offers a tolerance of ±20%. It is certified to AEC-Q200 standards, indicating suitability for automotive environments. The device incorporates FlexiCap technology with a nickel barrier to enhance mechanical robustness against board flexing.

Feature Summary

• Incorporates FlexiCap technology with a nickel barrier to provide enhanced resistance to mechanical stress and board flexing.
• Certified to AEC-Q200 standards, ensuring reliability for demanding automotive electronic applications.
• Utilizes X7R dielectric material to maintain stable capacitance characteristics across a wide operating temperature range.

Applications

• Automotive electronics requiring AEC-Q200 compliance
• High-reliability circuit boards subject to mechanical stress
• Applications sensitive to board flexing during assembly or operation

Procurement Notes

Verify the complete part number including suffixes such as MSTE03, as these denote specific termination and packaging configurations. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the procurement channel provides traceable data sheets matching the exact manufacturing batch requirements for quality assurance purposes.

Selection Notes

Select this component when high mechanical durability is required alongside standard X7R performance characteristics. The FlexiCap design makes it suitable for rigid-flex PCBs or applications where substrate movement is anticipated. Verify that the 1206 footprint aligns with existing board layouts and that the 50V rating meets the circuit's maximum operational voltage requirements.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors engineered for superior mechanical strength. The series addresses common failure modes associated with traditional MLCCs under physical stress. The 1206Y prefix indicates the case size and voltage class within the manufacturer's broader portfolio of high-reliability ceramic capacitors.

Replacement Considerations

Direct substitutes must match the 1206 package, 150nF capacitance, 50V rating, X7R dielectric, and AEC-Q200 certification. Verify that alternative components also feature FlexiCap or equivalent mechanical reinforcement technologies if board flex resistance is a critical design constraint.
