1812Y2000223MXTE03

Overview

The Knowles Syfer 1812Y2000223MXTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for high-frequency noise suppression. It features a capacitance of 0.022 µF and a voltage rating of 200 VDC. The component operates within a temperature range of -55°C to +125°C and supports a continuous current of 50 mA. Housed in an 1812 (4532 metric) surface-mount package, it integrates a built-in resistor structure to provide effective electromagnetic interference (EMI) filtering directly on the signal line.

Feature Summary

• Integrates a resistive element within the capacitor structure for simultaneous decoupling and damping.
• Provides effective EMI/RFI noise suppression in high-speed signal paths.
• Supports continuous DC current flow without blocking the signal path.

Applications

• High-speed digital interface filtering
• USB and HDMI signal line protection
• General EMI suppression in compact electronics

Procurement Notes

Verify the specific suffix 'E03' against the manufacturer's latest datasheet to confirm pinout orientation and termination specifications. Ensure the design accommodates the 50 mA continuous current limit and the thermal dissipation requirements associated with the integrated resistive element during operation.

Selection Notes

Select this component when a single device must handle both signal integrity filtering and power delivery. Unlike standard capacitors, this part allows DC current passage while attenuating high-frequency noise. Verify that the 200 VDC rating exceeds the maximum circuit voltage and that the 0.022 µF value aligns with the target frequency attenuation requirements.

Part Context

This component belongs to the Knowles Syfer feed-through capacitor family, which combines MLCC technology with resistive elements. These parts are engineered for applications requiring compact footprints and high-performance noise reduction in sensitive electronic circuits, offering a solution that replaces separate resistor-capacitor networks.

Replacement Considerations
