1812Y2000153MXTE03

Overview

The Knowles Syfer 1812Y2000153MXTE03 is a multilayer ceramic capacitor (MLCC) in the FlexiCap series, designed for board-flex sensitive applications. It features a capacitance of 15 nF with a ±20% tolerance and a DC voltage rating of 200 V. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) surface-mount package, it incorporates flexible terminals to mitigate mechanical stress during PCB flexing.

Feature Summary

• Flexible terminal construction reduces mechanical stress on the capacitor body during printed circuit board flexing.
• X7R dielectric provides stable capacitance characteristics across a wide operating temperature range.
• Designed specifically for board-flex sensitive automotive and industrial applications.

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Applications involving printed circuit board flexing
• General-purpose high-reliability surface mount circuits

Procurement Notes

Verify the specific suffix 'E03' against official datasheets to confirm terminal plating and barrier layer specifications. Ensure compatibility with reflow soldering profiles specified by the manufacturer. Confirm RoHS3 compliance status for current production runs. Validate that the 1812 footprint matches the design layout constraints.

Selection Notes

Select this component when board flex resistance is critical. The 200V rating suits medium-voltage DC applications. Compare with standard MLCCs if mechanical robustness is required. Consider the 15nF value for decoupling or filtering roles where stability under thermal variation is necessary.

Part Context

This part belongs to the Knowles Syfer FlexiCap family, which specializes in flexible termination technology. The 1812Y prefix indicates the 1812 case size and general product line. The MXTE03 suffix defines specific electrical and physical attributes including the nickel barrier and terminal configuration.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 15nF capacitance, 200V rating, X7R dielectric, and flexible terminal structure. Verify that alternative parts also meet AEC-Q200 standards if used in automotive contexts.
