SBSMC1000334MXR

Overview

The Knowles Syfer SBSMC1000334MXR is a feed-through capacitor designed for EMI filtering applications. It features a capacitance of 0.33 µF with a voltage rating of 100V and a tolerance of ±20%. The component utilizes an X7R dielectric material and operates within a temperature range of -55°C to +125°C. Packaged in a 2220 (5750 metric) footprint, it supports a current handling capacity of 20 A and provides an insertion loss of 43 dB at 100 MHz.

Feature Summary

• Integrated EMI filtering capability through feed-through architecture
• High current handling capacity suitable for power line applications
• Effective noise suppression with specified insertion loss performance

Applications

• EMI filter circuits
• Power supply input stages
• Noise suppression in high-current environments

Procurement Notes

Verify the specific package dimensions and terminal configuration against your PCB layout requirements. Confirm that the 20 A current rating aligns with your circuit's operational limits. Ensure the 100 VDC rating exceeds the maximum expected voltage in your application. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when integrated EMI filtering and high current handling are required in a compact form factor. Consider the 2220 footprint size relative to available board space. Evaluate the 43 dB insertion loss at 100 MHz against your specific noise spectrum requirements. Compare alternative feed-through capacitors if different mounting styles or higher voltage ratings are needed.
