1206Y2000102MSTE03

Overview

The Knowles Syfer 1206Y2000102MSTE03 is a multilayer ceramic capacitor (MLCC) in a 1206 surface-mount package. It features a capacitance of 1000 pF with a tolerance of ±20% and a DC voltage rating of 200 V. The component utilizes X7R dielectric material and is AEC-Q200 qualified for automotive reliability. It incorporates FlexiCap technology with a nickel barrier electrode structure to enhance mechanical robustness against board flexing.

Feature Summary

• FlexiCap flexible terminal design reduces stress on the ceramic body during PCB deformation
• Nickel barrier electrode construction provides enhanced durability and solderability
• X2Y internal architecture offers integrated filtering capabilities within a single compact footprint

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Circuit boards susceptible to mechanical flexing or vibration
• High-reliability signal conditioning and noise suppression circuits

Procurement Notes

Verify the specific suffix STE03 confirms the nickel barrier and X2Y configuration, as standard Y-series parts may differ. Confirm RoHS compliance status directly with the manufacturer documentation. Ensure the reel packaging quantity matches your assembly line requirements. Validate that the 200V rating meets your circuit's peak voltage demands under all operating conditions.

Selection Notes

Select this component when board flex resistance is critical for maintaining capacitance stability. The X7R dielectric provides stable performance across a wide temperature range suitable for general industrial and automotive use. Consider the 1206 footprint constraints and ensure the 1000 pF value aligns with your filtering or decoupling needs without compromising voltage headroom.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, designed specifically for high-reliability applications where mechanical integrity is paramount. The 1206Y prefix indicates the standard 1206 metric case size. The product line emphasizes durability through specialized electrode materials and flexible terminations to prevent cracking in dynamic environments.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 200V rating, 1000 pF capacitance, and X7R dielectric. Verify if the replacement also includes FlexiCap/Nickel Barrier features; otherwise, mechanical reliability may be compromised. Cross-reference AEC-Q200 certification if used in automotive contexts.
