1812Y0500404MXTE03

Overview

The Knowles Syfer 1812Y0500404MXTE03 is a multilayer ceramic capacitor (MLCC) in the FlexiCap series, designed for surface-mount technology. It features an X7R dielectric with a capacitance of 400 nF and a voltage rating of 50 VDC. The component utilizes a 1812 (4532 metric) package size and offers a tolerance of ±20%. It incorporates flexible end terminations to enhance mechanical reliability under stress.

Feature Summary

• X2Y architecture providing integrated common-mode noise filtering capabilities
• Flexible end terminations designed to absorb mechanical stress and prevent cracking
• High-reliability construction suitable for demanding electronic environments

Applications

• High-reliability general-purpose circuits
• Noise suppression in sensitive signal lines
• Common-mode interference mitigation in data interfaces

Procurement Notes

Verify the complete part number including the suffix MXTE03 to ensure correct termination style and packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure compatibility with standard SMT reflow profiles specified in the datasheet.

Selection Notes

Select this component when combined decoupling and EMI filtering are required in a single footprint. The X2Y design reduces board space compared to discrete components. Verify that the 50V rating meets circuit requirements and that the X7R temperature characteristics align with operational thermal conditions.

Part Context

This component belongs to the Knowles Syfer FlexiCap family, which specializes in robust MLCCs with flexible terminations. The 1812Y prefix indicates the X2Y topology within the 1812 package dimension. This series targets applications requiring enhanced durability against board flexing and vibration.

Replacement Considerations

Direct substitutes must match the 1812Y X2Y form factor and FlexiCap termination style. Verify equivalent capacitance, voltage rating, and dielectric type before substitution.
