1206Y1000333MSTE03

Overview

The Knowles Syfer 1206Y1000333MSTE03 is a high-reliability multilayer ceramic capacitor (MLCC) in a 1206 surface-mount package. It features a capacitance of 33 nF with a tolerance of ±20% and a DC voltage rating of 100 VDC. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. This part belongs to the FlexiCap series, characterized by flexible terminals designed to reduce mechanical stress on the substrate.

Feature Summary

• Flexible terminal construction minimizes board flex-induced cracking
• Nickel barrier electrode technology enhances reliability
• X2Y architecture provides integrated EMI filtering capabilities

Applications

• Automotive electronics requiring AEC-Q200 qualification
• Board-flex sensitive circuit designs
• High-reliability industrial applications

Procurement Notes

Verify the complete ordering code including suffixes such as MSTE03 against official manufacturer documentation to ensure correct termination and packaging specifications. Confirm RoHS compliance status and specific reel quantities prior to procurement. Cross-reference datasheet revisions to validate current manufacturing status and availability constraints for this specific variant.

Selection Notes

Select this component when board flexibility is a primary concern due to its specialized flexible terminal design. The X7R dielectric offers a balance of capacitance density and temperature stability suitable for general decoupling. Ensure the 1206 footprint aligns with PCB layout constraints and that the 100V rating exceeds the maximum circuit voltage under all operating conditions.

Part Context

This capacitor is part of the Knowles Syfer FlexiCap family, engineered specifically for automotive and high-reliability sectors. The series integrates nickel barrier technology to improve solder joint integrity and long-term durability. As an X2Y device, it combines three-terminal functionality within a standard two-terminal footprint structure for enhanced noise suppression.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 100V rating, 33nF capacitance, and X7R dielectric. Verify if alternative parts support the required flexible terminal characteristics and AEC-Q200 certification. Standard MLCCs lacking nickel barrier or flexible terminations may not be suitable replacements for board-flex sensitive applications.
