1206Y0500123MSTE03

Overview

The Knowles Syfer 1206Y0500123MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in a 1206 package. It features a capacitance of 12 nF with a tolerance of ±20% and a DC voltage rating of 50 V. The dielectric material is X7R, providing stability across an operating temperature range of -55°C to +125°C. This component utilizes FlexiCap technology with a nickel barrier for enhanced mechanical reliability.

Feature Summary

• Incorporates FlexiCap flexible terminal technology combined with a nickel barrier structure to improve resistance to mechanical stress and board flexing.

Applications

• Automotive electronics requiring AEC-Q200 qualification
• High-reliability circuit boards sensitive to mechanical strain
• General-purpose decoupling and filtering in SMD/SMT assemblies

Procurement Notes

Verify the specific suffix MSTE03 against official Knowles Syfer documentation to confirm the inclusion of the nickel barrier and FlexiCap terminals. Ensure compatibility with RoHS3 standards and confirm availability status through authorized distributors, as supply may be restricted in certain regions.

Selection Notes

Select this component when high mechanical robustness is required alongside standard X7R performance characteristics. The 1206 footprint offers a balance between capacitance density and physical size. Confirm that the 50V rating meets the circuit's maximum DC bias requirements.

Part Context
