1812Y0500404MXTE07

Overview

The Knowles Syfer 1812Y0500404MXTE07 is a feedthrough capacitor with an X2Y architecture, housed in an 1812 (4532 metric) surface-mount package. It features a capacitance of 0.4 µF and a DC voltage rating of 50 V. The dielectric material is X7R, providing a tolerance of ±20%. Designed for high-frequency noise suppression, it utilizes a three-terminal configuration to minimize parasitic inductance.

Feature Summary

• Integrates X2Y technology within a single component to provide common-mode and differential-mode filtering capabilities simultaneously.
• Utilizes a three-terminal feedthrough structure to significantly reduce parasitic inductance compared to standard two-terminal capacitors.
• Employs flexible end-termination technology to enhance mechanical reliability and resistance to board flexing stresses.

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• EMI suppression in compact electronic modules

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before integration. Confirm that the 1812 footprint dimensions align with your PCB layout constraints. Ensure the 50V rating meets the peak operating voltage requirements of the target circuit application.

Selection Notes

Select this component when space-constrained designs require superior high-frequency performance compared to discrete filter networks. The X2Y architecture offers a compact alternative to multiple capacitors. Evaluate the thermal management requirements as the device operates within a -55°C to +125°C range. Consider the soldering profile compatibility with the flexible termination materials.
