SBSMC5000683MXT

Overview

The Knowles Syfer SBSMC5000683MXT is a surface-mount feedthrough capacitor designed for EMI suppression. It features a capacitance of 0.047 µF with a ±20% tolerance and an X7R temperature coefficient. The component is rated for 500 V DC and supports a continuous current of 20 A. Housed in a 2220 (5750 metric) package, it measures 5.70 mm x 5.00 mm with a maximum height of 3.38 mm. It provides 43 dB attenuation at 100 MHz and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated feedthrough architecture providing high-frequency noise attenuation in a compact SMD form factor
• High current handling capability suitable for power line filtering applications
• Stable X7R dielectric material ensuring consistent performance across wide temperature variations

Applications

• Power supply input filtering
• DC bus noise suppression
• General EMI/RFI mitigation in electronic circuits

Procurement Notes

Verify the specific suffix and marking code against the manufacturer's latest datasheet to ensure compatibility with your design requirements. Confirm that the 2220 footprint matches your PCB layout constraints. Check RoHS3 compliance status if required by your environmental regulations. Ensure the 20 A current rating exceeds your application's peak load demands.

Selection Notes

Select this component when high current capacity and effective EMI filtering are required in a single surface-mount device. The 500 V rating makes it suitable for higher voltage DC lines compared to lower-rated alternatives. Consider the 2220 package size for board space availability. Compare attenuation characteristics against other filter topologies if specific frequency response curves are critical.

Part Context

This part belongs to the SBSMC series of feedthrough capacitors from Knowles Syfer. These components combine the functions of a capacitor and a ground connection to suppress electromagnetic interference. The series is designed for robust performance in demanding environments, offering high reliability and stability for industrial and commercial electronics.

Replacement Considerations

Direct substitutes must match the 0.047 µF capacitance, 500 V rating, 20 A current, and 2220 package dimensions. Verify equivalent attenuation specifications at target frequencies. Ensure thermal and electrical ratings meet or exceed original requirements.
