SBSMC5000222MXT

Overview

The Knowles Syfer SBSMC5000222MXT is a surface-mount EMI feedthrough capacitor designed for high-frequency noise suppression. It features a capacitance of 2200 pF (2.2 nF) with a tolerance of ±20%. The component is rated for a maximum DC voltage of 500 V and can handle a continuous current of 20 A. Utilizing X7R dielectric material, it operates reliably within a temperature range of -55°C to +125°C. The device is housed in a 2220 (5750 Metric) package with three PCB pads, providing a compact solution for power line filtering applications.

Feature Summary

• Surface-mount feedthrough architecture for efficient EMI suppression
• High current handling capability suitable for power lines
• Stable X7R ceramic dielectric for consistent performance across temperatures

Applications

• Power supply input filtering
• DC motor drive circuits
• Industrial control systems

Procurement Notes

Verify the exact part number against manufacturer datasheets to ensure compatibility with specific circuit requirements. Confirm that the 2220 package dimensions and pad layout match the target PCB design. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the selected variant matches the required capacitance and voltage ratings for the intended application.

Selection Notes

Select this component when space-constrained designs require high-current EMI filtering on power rails. The surface-mount format facilitates automated assembly processes. Consider the 20 A current rating and 500 V voltage limit to ensure adequate safety margins. The X7R temperature coefficient provides reliable capacitance stability in varying thermal environments typical of industrial electronics.

Part Context

This component belongs to the SBSM series of feedthrough capacitors from Knowles Syfer. The series is engineered for robust electromagnetic interference reduction in compact electronic assemblies. These devices integrate capacitor functionality directly into the mounting structure, offering superior high-frequency performance compared to standard discrete capacitors.

Replacement Considerations

Direct substitutes include other SBSMC series variants with matching capacitance and package size. Verify that alternative parts maintain the same 20 A current rating and 500 V voltage specification. Ensure any replacement also utilizes X7R dielectric and fits the 2220 footprint.
