1806Y0500224MXTE07

Overview

The Knowles Syfer 1806Y0500224MXTE07 is a surface-mount feed-through capacitor designed for EMI filtering. It features an X7R dielectric with a capacitance of 0.22 µF and a DC voltage rating of 50V. The component utilizes a three-terminal C-filter architecture within an 1806 (4516 metric) package, measuring 1.6 mm in width and 1.1 mm in height. It offers a tolerance of ±20% and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Three-terminal C-filter topology for enhanced high-frequency noise attenuation
• Surface-mount construction compatible with automated assembly processes
• X7R ceramic dielectric providing stable capacitance across wide temperature variations

Applications

• High-density PCB layouts requiring compact EMI suppression
• Power supply input/output filtering stages
• Signal line protection against electromagnetic interference

Procurement Notes

Verify the specific suffix 'E07' against official datasheets to confirm reel packaging specifications and tape dimensions. Ensure the three-terminal configuration matches the target footprint, as standard two-terminal equivalents differ physically. Cross-reference RoHS compliance status directly with the manufacturer's current documentation before finalizing procurement orders.

Selection Notes

Select this component when board space constraints necessitate a small 1806 footprint alongside superior high-frequency performance compared to standard MLCCs. The three-terminal design provides better isolation between input and output grounds. Confirm that the 50V rating sufficiently exceeds the maximum circuit operating voltage to ensure long-term reliability under thermal stress.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which integrates capacitive elements into a single conductive housing. Unlike discrete components, these units minimize parasitic inductance by shortening internal current paths. The 1806Y series specifically targets applications demanding robust EMI mitigation in constrained surface-mount environments.
