Overview
The Knowles Syfer 1206Y2000153MSTE03 is a high-reliability multilayer ceramic capacitor (MLCC) in a 1206 (3216 metric) surface-mount package. It features a capacitance of 15 nF with a tolerance of ±20% and a DC voltage rating of 200 VDC. The component utilizes X7R dielectric material and is qualified to AEC-Q200 standards for automotive applications. It incorporates FlexiCap technology with a nickel barrier, providing enhanced mechanical flexibility and resistance to board bending.
Feature Summary
- FlexiCap termination technology provides superior mechanical performance and increased tolerance to board bending compared to conventional capacitors.
- Nickel barrier construction enhances reliability and supports high-temperature cycling stability.
- AEC-Q200 qualification ensures suitability for demanding automotive electronic environments.
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 specific suffix MSTE03 against official Knowles Syfer documentation to confirm the presence of the nickel barrier and FlexiCap termination. Ensure compatibility with existing PCB footprints designed for standard 1206 MLCCs, as terminal dimensions may differ slightly due to the flexible termination structure. Confirm RoHS compliance status through current manufacturer declarations.
Selection Notes
Select this component when high mechanical robustness is required alongside standard X7R temperature characteristics. The 200V rating and 15nF value suit decoupling or filtering roles in automotive systems. Consider the FlexiCap feature if the design involves rigid-flex boards or environments prone to physical vibration and bending stresses that might crack standard terminations.
Part Context
This part belongs to the Knowles Syfer FlexiCap series, which specializes in flexible termination MLCCs. The series is engineered to withstand significant board deflection without cracking, addressing common failure modes in traditional ceramic capacitors. The 1206Y prefix indicates the 1206 case size within the Y-series lineup.
