SBSMP5000472MXT

Overview

The Knowles Syfer SBSMP5000472MXT is a surface-mount LC (Pi) EMI filter capacitor designed for high-frequency noise suppression. It features a capacitance of 4700 pF with a ±20% tolerance and an X7R dielectric material. The component is rated for 500 V DC and supports a continuous current of 10 A. Housed in a 2220 (5750 metric) package with three PCB terminals, it measures 5.70 mm in length, 5.00 mm in width, and 3.30 mm in height. It provides 44 dB attenuation at 100 MHz and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates LC Pi-filter topology for enhanced low-pass filtering performance
• Supports high continuous current handling capabilities
• Provides significant insertion loss for effective EMI/RFI suppression
• Utilizes robust X7R ceramic dielectric for stable electrical characteristics

Applications

• General-purpose EMI filtering in electronic circuits
• Power line noise suppression in compact devices
• Signal integrity protection in high-speed data interfaces

Procurement Notes

Verify the complete part number including the suffix MXT to ensure correct tape-and-reel packaging configuration. Confirm RoHS3 compliance requirements against specific project environmental standards. Check manufacturer documentation for any recent product change notices or end-of-life announcements prior to finalizing procurement plans.

Selection Notes

Select this component when space-constrained designs require integrated filtering without discrete inductors. The 2220 footprint offers a balance between current capacity and board area. Ensure the operating voltage remains below the 500V DC rating and that thermal conditions stay within the specified -55°C to +125°C range for reliable long-term operation.

Part Context

This component belongs to the SBSMP series of surface-mount feedthrough capacitors from Knowles Syfer. These parts are engineered to replace traditional discrete LC networks, simplifying assembly while maintaining high-performance filtering. The series is characterized by its ability to handle significant current loads in small form factors suitable for modern electronics manufacturing.

Replacement Considerations

Direct substitutes include the SBSGP5000472MXT and SBSMC5000473MXT from the same manufacturer family. Verify pinout compatibility and physical dimensions before substitution. Alternative manufacturers may offer similar specifications but require validation of mounting hole patterns and thermal performance.
