SBSMC2000154MXT

Overview

The Knowles Syfer SBSMC2000154MXT is a surface-mount EMI feedthrough capacitor designed for high-frequency noise suppression. It features a capacitance of 150 nF with a ±20% tolerance and operates at a DC voltage rating of 200 V. The component utilizes an X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Packaged in a 6.6x5 mm footprint, it supports a maximum current of 20 A and provides significant insertion loss, effectively filtering electromagnetic interference in compact electronic assemblies.

Feature Summary

• Surface-mount EMI feedthrough design for efficient PCB integration
• High current handling capability suitable for power line filtering
• Stable X7R ceramic dielectric for consistent electrical characteristics

Applications

• Electromagnetic interference filtering in power supply circuits
• Noise suppression in high-density electronic assemblies
• Signal integrity protection in communication equipment

Procurement Notes

Verify the specific suffix MXT corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 200V DC rating and 150nF capacitance align with the target circuit's operational parameters. Ensure compatibility with standard reflow soldering profiles for surface-mount components to maintain device integrity during manufacturing.

Selection Notes

Select this component when space-constrained designs require effective EMI filtering without through-hole mounting. The 20A current rating makes it suitable for applications involving moderate power levels. Consider the X7R temperature coefficient if operating environments experience significant thermal fluctuations. Evaluate the 6.6x5mm footprint against available board real estate to ensure proper placement and clearance.
