1812Y2000823MXTE03

Overview

The Knowles Syfer 1812Y2000823MXTE03 is a multilayer ceramic capacitor (MLCC) featuring an X7R dielectric and a capacitance of 82 nF. It operates at a DC voltage rating of 200V with a tolerance of ±20%. The component utilizes the FlexiCap™ technology, incorporating flexible end terminations to enhance mechanical reliability under board flex conditions. It is housed in an 1812 (4532 metric) surface-mount package.

Feature Summary

• FlexiCap™ flexible end termination design for enhanced board flex reliability
• X2Y architecture providing integrated common-mode noise suppression
• Nickel barrier layer construction for improved solderability and corrosion resistance

Applications

• Automotive electronics requiring AEC-Q200 qualification
• Circuit boards subject to mechanical stress or flexing
• High-frequency signal lines requiring EMI filtering

Procurement Notes

Verify that the specific MXTE03 suffix matches the required nickel barrier and X2Y configuration. Confirm that the 1812 footprint aligns with the PCB layout constraints. Ensure the application environment remains within the specified -55°C to +125°C operating temperature range for reliable performance.

Selection Notes

Select this component when standard MLCCs fail due to board flex-induced cracking. The X2Y topology offers superior high-frequency noise attenuation compared to single-terminal capacitors. Verify that the 200V rating provides adequate margin for the target circuit's peak voltage levels.

Part Context

This part belongs to the Knowles Syfer Y-series, which specializes in high-reliability capacitors for automotive and industrial sectors. The series integrates X2Y functionality into standard SMD packages, combining decoupling and filtering capabilities in a single compact component suitable for space-constrained designs.

Replacement Considerations

Direct substitutes include 1812Y2000823JET and 1812Y2000823MXTE03 variants from the same manufacturer family.
