SBSGP5000473MXB

Overview

The Knowles Syfer SBSGP5000473MXB is a surface-mount EMI network filter featuring a Pi filter circuit topology. It provides a capacitance of 0.047 µF with a voltage rating of 500 V and a tolerance of ±20%. The component utilizes X7R dielectric material and supports a current rating of 5 A. Housed in a 2012 (5232 metric) package measuring 5.25 mm x 3.2 mm x 2.5 mm, it offers an attenuation of 39 dB. Designed for operation between -55°C and +125°C, it is supplied in reel packaging.

Feature Summary

• Integrates a third-order low-pass Pi filter circuit within a compact surface-mount footprint.
• Provides high-voltage isolation capability rated at 500 V DC.
• Utilizes X7R ceramic dielectric for stable performance across a wide industrial temperature range.

Applications

• General-purpose EMI suppression in electronic circuits
• Signal line filtering in power management systems
• Noise reduction in communication interfaces

Procurement Notes

Verify the specific suffix MXB against official datasheets to confirm package dimensions and termination specifications. Ensure compatibility with standard SMT reflow profiles and check RoHS compliance status prior to integration. Confirm that the 5 A current rating aligns with the application's peak load requirements to prevent thermal degradation.

Selection Notes

Select this component when a compact, high-voltage EMI filter is required for signal lines. The Pi topology offers superior attenuation compared to single-capacitor solutions. Verify that the 2012 package size fits the PCB layout constraints and that the 500 V rating exceeds the system's maximum operating voltage plus safety margins.

Part Context

This part belongs to the SBSG series of surface-mount EMI filters from Knowles Syfer. The series focuses on providing integrated filtering solutions in small footprints. The SBSGP variant specifically denotes the Pi filter configuration, distinguishing it from other topologies within the broader product family.

Replacement Considerations
