SBSMC5000472MXT

Overview

The Knowles Syfer SBSMC5000472MXT is a surface-mount feedthrough capacitor designed for high-frequency noise suppression. It features a capacitance of 4700 pF with a voltage rating of 500 VDC and a tolerance of ±20%. The component utilizes an X7R dielectric material, ensuring stability across an operating temperature range from -55°C to +125°C. Housed in a 2220 (5750 metric) package with three printed circuit board pads, it supports a current rating of 20 A. This Class 1 device provides effective electromagnetic interference filtering in compact electronic assemblies.

Feature Summary

• Integrates feedthrough capacitor architecture within a standard surface-mount footprint for simplified PCB layout.
• Provides significant attenuation of high-frequency electromagnetic interference signals.
• Supports high continuous current handling capabilities suitable for power line applications.

Applications

• Electromagnetic interference filtering in general-purpose electronic circuits
• Power supply input stages requiring high-voltage isolation and noise reduction
• Signal conditioning in industrial control systems

Procurement Notes

Verify the specific suffix MXT indicates reel packaging when sourcing. Confirm the manufacturer part number matches exactly to ensure correct X7R dielectric and 2220 package dimensions. Check for recent product discontinuation notifications or lifecycle changes directly from Knowles Syfer documentation before finalizing procurement plans.

Selection Notes

Select this component when a single SMD package must replace discrete feedthrough capacitors to save board space. Ensure the application requires 500 VDC rating and 20 A current capacity. Verify that the 4700 pF capacitance value aligns with the target filter frequency response requirements for the specific EMI spectrum being addressed.
