SBSGC5000223MXT

Overview

The Knowles Syfer SBSGC5000223MXT is a surface mount C and PI filter capacitor designed for EMI suppression. It features a capacitance of 22 nF with a ±20% tolerance, utilizing X7R dielectric material. The component is rated for 500 VDC and operates within a temperature range of -55°C to +125°C. Packaged in an 1812 (4532 metric) footprint with three PCB pads, it integrates feedthrough technology to provide effective noise filtering in compact electronic assemblies.

Feature Summary

• Integrates C and PI filter topologies for enhanced electromagnetic interference suppression
• Utilizes feedthrough construction to minimize parasitic inductance
• Supports surface mount assembly on three-pad configurations

Applications

• High-frequency signal line filtering
• Power supply input noise reduction
• EMI suppression in sensitive analog circuits

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Confirm that the 1812 package dimensions and three-pad terminal layout match the target PCB footprint requirements. Ensure the 500V DC rating and X7R temperature characteristics align with the operational environment constraints of the final application design.

Selection Notes

Select this component when high-density EMI filtering is required in space-constrained designs. The integrated PI filter structure offers superior attenuation compared to discrete single capacitors. Consider the 1812 package size relative to available board real estate. Verify that the 22 nF capacitance value provides adequate filtering for the target frequency spectrum without impacting circuit stability or power delivery requirements.

Part Context

This part belongs to the SBSG series of surface mount feedthrough capacitors from Knowles Syfer. These components are engineered for high-reliability applications requiring robust EMI performance. The series utilizes advanced ceramic materials to maintain stable electrical characteristics across wide temperature ranges, supporting demanding industrial and commercial electronics environments.

Replacement Considerations

Cross-reference with other SBSG series variants such as SBSGC5000152MXT or SBSGC5000332MXT if different capacitance values are needed. Verify pinout compatibility and physical dimensions before substituting with components from other manufacturers.
