1206Y0500184MSTE03

Overview

The Knowles Syfer 1206Y0500184MSTE03 is a Surface Mount Multilayer Ceramic Capacitor (MLCC) in a 1206 (3216 metric) package. It features a capacitance of 0.18 µF with a ±20% tolerance and an X7R dielectric. The rated DC voltage is 50V. This component is AEC-Q200 qualified and utilizes FlexiCap technology with a nickel barrier for enhanced reliability. It is classified as an X2Y capacitor, designed to provide common-mode noise suppression.

Feature Summary

• X2Y architecture integrates three terminals into a single surface mount device for effective common-mode filtering.
• FlexiCap construction incorporates a nickel barrier layer to improve mechanical robustness against board flexing.
• AEC-Q200 qualification ensures compliance with automotive electronic component stress testing standards.

Applications

• Automotive electronics requiring AEC-Q200 certified components
• Noise suppression in sensitive signal lines
• Common-mode interference reduction in high-reliability circuits

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm terminal configuration and barrier material specifications. Ensure that the X2Y topology aligns with the circuit design requirements for common-mode filtering rather than standard decoupling. Confirm RoHS compliance status through current regulatory documentation before integration.

Selection Notes

Select this component when a compact solution for common-mode noise attenuation is required in space-constrained designs. The X2Y structure offers superior performance compared to discrete capacitors for EMI suppression. Consider the 50V rating and X7R temperature characteristics relative to the operating environment. Verify compatibility with automated assembly processes due to the specific terminal arrangement.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which emphasizes durability in flexible printed circuit applications. The 1206Y prefix indicates the 1206 case size within their product line. The MSTE03 suffix denotes specific manufacturing details regarding the termination and barrier materials, distinguishing it from standard MLCC variants.

Replacement Considerations

Direct substitutes must match the X2Y topology and 1206 footprint. Standard three-terminal capacitors may not provide equivalent common-mode rejection. Verify that alternative parts meet AEC-Q200 requirements if used in automotive contexts. Check for identical voltage and capacitance ratings to ensure circuit functionality remains unchanged.
