1812Y0500822MSTE03

Overview

The Knowles Syfer 1812Y0500822MSTE03 is a multilayer ceramic capacitor (MLCC) in an 1812 surface-mount package. It features an X7R dielectric with a capacitance of 8200 pF and a voltage rating of 50 VDC. The component offers a tolerance of ±20% and operates within a temperature range of -55°C to +125°C. It incorporates FlexiCap technology with a nickel barrier for enhanced mechanical reliability.

Feature Summary

• X2Y architecture providing integrated common-mode filtering capabilities
• FlexiCap soft termination design to withstand board flexing stress
• Nickel barrier layer protecting the internal electrode structure
• AEC-Q200 qualification for automotive grade reliability

Applications

• Automotive electronic circuits requiring board-flex resilience
• Common-mode noise suppression in sensitive signal lines
• High-reliability systems subject to mechanical vibration

Procurement Notes

Verify the specific suffix MSTE03 against official datasheets to confirm the inclusion of the nickel barrier and X2Y configuration. Ensure compatibility with reflow profiles specified for FlexiCap terminations. Confirm AEC-Q200 status if automotive compliance is mandatory for the target application.

Selection Notes

Select this component when standard MLCCs fail due to board flex-induced cracking. The X2Y topology simplifies designs by combining decoupling and filtering functions. Verify that the 50V rating meets circuit requirements, as higher voltage variants exist within the same series.

Part Context

This part belongs to the Knowles Syfer 1812Y series, which specializes in high-reliability capacitors for harsh environments. The series utilizes proprietary FlexiCap technology to improve durability compared to traditional silver-terminated devices.

Replacement Considerations

Substitutes must match the 1812 footprint, 50V rating, and X2Y functionality. Generic X7R capacitors lack the nickel barrier and soft termination, risking failure under mechanical stress.
