1812Y0500444MXTE03

Overview

The Knowles Syfer 1812Y0500444MXTE03 is a multilayer ceramic capacitor featuring X2Y architecture within an 1812 surface-mount package. It offers a capacitance of 0.44 µF with a DC voltage rating of 50V and a tolerance of ±20%. Utilizing X7R dielectric material, the component operates reliably between -55°C and +125°C. The device integrates passive filtering capabilities directly into the capacitor structure, providing common-mode noise suppression alongside standard decoupling functions for high-density circuit designs.

Feature Summary

• Integrates X2Y passive filtering technology to suppress common-mode noise within the capacitor structure
• Provides simultaneous decoupling and EMI filtering in a compact surface-mount footprint
• Utilizes flexible terminal construction to enhance mechanical reliability under board flex conditions

Applications

• High-speed digital signal line protection
• Power supply input/output decoupling
• EMI suppression in sensitive electronic circuits

Procurement Notes

Verify the complete part number including the IPC-E03 designation to ensure correct X2Y configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Validate that the 50V rating meets the specific circuit requirements for both DC bias and transient conditions.

Selection Notes

Select this component when space constraints require combined filtering and decoupling functions. The X2Y design reduces the total component count compared to discrete filter arrangements. Ensure the application environment remains within the specified temperature range to maintain capacitance stability and long-term reliability.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which emphasizes mechanical robustness. The 1812Y series specifically targets applications requiring reliable performance in environments subject to mechanical stress. The X2Y variant provides enhanced electromagnetic interference mitigation without increasing the board area.
