1806Y0500204MXTE01

Overview

The Knowles Syfer 1806Y0500204MXTE01 is a feed-through capacitor designed for surface mount technology. It features a capacitance of 0.2 µF (200 nF) with a DC voltage rating of 50 VDC and a tolerance of ±20%. The component utilizes an X7R dielectric material, ensuring stability across a wide temperature range from -55°C to +125°C. It operates in the 1806 (4516 metric) package size and includes a bottom end seal configuration. The device supports a current rating of 300 mA and is supplied in reel packaging.

Feature Summary

• Integrates feed-through filtering capabilities within a standard surface-mount footprint
• Utilizes X7R dielectric for reliable performance across industrial temperature ranges
• Features a bottom end seal design for secure mechanical mounting

Applications

• EMI filtering in compact electronic assemblies
• Power line conditioning for low-voltage circuits
• Signal integrity protection in SMT-based designs

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm exact sealing and termination specifications. Ensure compatibility with automated placement equipment regarding the reel packaging format. Cross-reference the 1806 footprint dimensions with PCB layout guidelines to maintain proper clearance and soldering standards during assembly processes.

Selection Notes

Select this component when a feed-through topology is required within a constrained 1806 surface-mount area. The 50V rating suits low-voltage applications, while the X7R dielectric offers a balance of capacitance density and thermal stability. Consider the 300mA current limit when designing power paths to ensure the device remains within its operational safety margins under load conditions.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor portfolio, which combines passive filtering with structural mounting. These components are engineered to replace traditional discrete filters by integrating the capacitor and terminal into a single ceramic body. The series is designed for high-reliability environments requiring robust EMI suppression in space-constrained printed circuit board layouts.
