1812Y0500823MSTE03

Overview

The Knowles Syfer 1812Y0500823MSTE03 is a multilayer ceramic capacitor (MLCC) in an 1812 (4532 metric) surface-mount package. It features a capacitance of 0.082 µF with a ±20% tolerance and a rated DC voltage of 50V. The dielectric material is X7R, providing stable performance across a temperature range of -55°C to +125°C. This component belongs to the FlexiCap series, designed for board-flex sensitive applications, and meets AEC-Q200 automotive qualification standards.

Feature Summary

• X2Y architecture provides integrated common-mode noise filtering within a single compact footprint
• FlexiCap soft termination technology enhances mechanical reliability under board flex stress
• Nickel barrier electrode structure ensures robust solderability and long-term stability
• AEC-Q200 qualified for high-reliability automotive electronic environments

Applications

• Automotive infotainment systems requiring EMI suppression
• Power supply input/output filtering in vehicle electronics
• Data bus lines sensitive to common-mode interference
• Board-flex critical automotive modules

Procurement Notes

Verify the complete part number including the suffix MSTE03 to confirm the X2Y configuration and nickel barrier construction. Ensure compatibility with reflow soldering profiles specified in the official datasheet. Confirm RoHS3 compliance status if required by specific regional regulations or customer specifications before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require combined decoupling and filtering functions. The X2Y topology reduces component count compared to discrete solutions. Consider the 50V rating and X7R dielectric characteristics for general-purpose automotive applications where moderate capacitance stability over temperature is sufficient.

Part Context

This part belongs to the Knowles Syfer 1812Y series, specifically the FlexiCap line optimized for automotive durability. The 'Y' indicates the 1812 case size, while '050' denotes the 50V rating. The 'MSTE03' suffix identifies the specific X2Y variant with nickel barrier terminations, distinguishing it from standard MLCCs in the same family.

Replacement Considerations

Direct substitutes must match the X2Y topology and 1812 footprint. Standard X7R MLCCs lack the integrated filtering capability. Verify terminal metallurgy and flex-rating requirements when considering alternatives from other manufacturers.
