1812Y1000183MSTE03

Overview

The Knowles Syfer 1812Y1000183MSTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a capacitance of 0.018 µF with a tolerance of ±20% and a rated DC voltage of 100V. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) package, it incorporates FlexiCap technology with a nickel barrier electrode structure. This part is AEC-Q200 qualified and functions as an X2Y capacitor.

Feature Summary

• X2Y architecture providing integrated common-mode noise suppression
• FlexiCap soft termination design to enhance board flex resilience
• Nickel barrier electrode construction for improved reliability
• AEC-Q200 qualification for automotive grade standards

Applications

• Automotive electronics requiring board flex sensitivity
• High-frequency noise filtering in sensitive circuits
• Common-mode interference suppression in data lines

Procurement Notes

Verify the specific suffix MSTE03 against official datasheets to confirm the X2Y configuration and FlexiCap termination type. Ensure compatibility with reflow soldering profiles specified for soft-termination components. Confirm AEC-Q200 certification requirements match the target application's automotive or industrial standards before finalizing procurement.

Selection Notes

Select this component when space-constrained designs require combined decoupling and EMI filtering capabilities. The 1812 footprint allows for higher capacitance density compared to smaller packages. Consider the X2Y topology for applications needing reduced component count by integrating filtering directly into the capacitor structure rather than using discrete inductors or ferrites.

Part Context

This part belongs to the Knowles Syfer 1812Y series, which specializes in high-voltage and high-reliability MLCCs. The Y designation typically indicates specific voltage ratings and dielectric characteristics within the product line. The series is engineered for demanding environments where standard capacitors may fail due to mechanical stress or electrical noise.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 100V rating, 0.018µF value, and X2Y functionality. Generic X7R capacitors lack the integrated filtering and soft termination features. Verify pinout and electrical characteristics carefully if considering alternative manufacturers.
