1812J2000184MXTE03

Overview

The Knowles Syfer 1812J2000184MXTE03 is a surface-mount multilayer ceramic capacitor (MLCC) featuring an X7R dielectric and a capacitance of 180 nF. It operates at a DC voltage rating of 200 V with a tolerance of ±20%. The component utilizes a 1812 (4532 metric) case size and incorporates a nickel barrier electrode structure. It is designed for high-reliability applications, offering stable performance across a temperature range of -55°C to +125°C.

Feature Summary

• X2Y architecture providing integrated common-mode filtering capabilities within a single compact package
• Nickel barrier electrode construction ensuring robust solderability and long-term reliability
• High-temperature stability maintained through X7R dielectric characteristics

Applications

• Common-mode noise suppression in high-speed digital signal lines
• Power supply input/output filtering for EMI reduction
• General-purpose decoupling in automotive electronics

Procurement Notes

Verify the specific suffix 'E03' against official datasheets to confirm packaging details and terminal finish specifications. Ensure compatibility with standard reflow soldering profiles for nickel barrier terminations. Cross-reference RoHS compliance status directly with manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when space-constrained designs require combined decoupling and filtering functions. The 1812 footprint accommodates higher capacitance values compared to smaller packages. Consider the X2Y topology for simplified circuit layouts where traditional discrete filter components would increase board area and complexity.

Part Context

This part belongs to the Knowles Syfer XT series of high-reliability MLCCs. The series is engineered for demanding environments, including automotive and industrial sectors. The 1812J prefix indicates the 1812 case dimensions and general product line classification within the broader ceramic capacitor portfolio.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 200V rating, 180nF capacitance, and X2Y configuration. Verify that alternative X2Y capacitors maintain compatible nickel barrier termination styles for identical soldering processes.
