1206Y2000333MSTE03

Overview

The Knowles Syfer 1206Y2000333MSTE03 is a feed-through multilayer ceramic capacitor (MLCC) in a 1206 surface-mount package. It features a capacitance of 0.033 µF with a voltage rating of 200 VDC and a tolerance of ±20%. The component utilizes X7R dielectric material and is rated for operation between -55°C and +125°C. It incorporates FlexiCap technology with a nickel barrier termination system to enhance mechanical reliability under stress.

Feature Summary

• Integrated feed-through architecture providing internal shielding and electromagnetic interference suppression within the component body.
• FlexiCap termination design utilizing a nickel barrier to absorb mechanical stress and prevent solder joint cracking during board flexing.

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in automotive electronics
• EMI suppression circuits requiring compact form factors

Procurement Notes

Verify the specific suffix MSTE03 against official Knowles Syfer documentation to confirm the inclusion of FlexiCap termination and X7R dielectric characteristics. Ensure compatibility with automated pick-and-place equipment regarding the 1206 footprint dimensions. Confirm RoHS compliance status through current manufacturer declarations prior to integration into regulated assemblies.

Selection Notes

Select this component when space-constrained designs require integrated EMI filtering without additional discrete components. The 1206 case size offers a balance between current handling capability and board real estate efficiency. Consider the X7R temperature coefficient for applications where moderate capacitance stability across operating temperatures is acceptable.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability MLCCs designed for harsh environments. The series addresses common failure modes associated with mechanical stress on standard terminations, making it suitable for automotive and industrial sectors where vibration resistance is critical.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 200V rating, 0.033µF value, and specifically the FlexiCap/Nickel Barrier termination structure. Generic X7R capacitors lack the integrated feed-through shielding and mechanical stress relief features.
