SBSGC5000473MXB

Overview

The Knowles Syfer SBSGC5000473MXB 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 dielectric. The component is rated for 500 V DC and supports a continuous current of 10 A. Housed in an 1812 (4532 metric) package measuring 4.55mm x 3.20mm x 2.65mm, it provides 39 dB insertion loss at 100 MHz. Operating temperatures range from -55°C to +125°C.

Feature Summary

• Integrated C-filter topology for effective common-mode noise attenuation
• High current handling capability suitable for power line filtering applications
• Surface-mount construction optimized for automated PCB assembly processes

Applications

• EMI filtering in high-density electronic assemblies
• Power supply input stages requiring compact footprint solutions
• Signal integrity protection in sensitive communication interfaces

Procurement Notes

Verify the specific suffix MXB against official datasheets to confirm packaging and terminal configuration. Ensure compatibility with RoHS3 standards if required by your manufacturing environment. Cross-reference the 1812 package dimensions with your PCB land pattern to guarantee proper solder joint formation and mechanical stability during operation.

Selection Notes

Select this component when space constraints necessitate an 1812 footprint while maintaining high voltage ratings. The 10 A current rating distinguishes it from lower-capacity variants. Consider the X7R temperature coefficient for stable performance across industrial operating ranges. Validate that the 39 dB attenuation meets system-specific EMI requirements at target frequencies.

Part Context

This part belongs to the SBSG series of EMI network filters manufactured by Knowles Syfer. The series utilizes advanced ceramic technologies to provide reliable filtering in compact form factors. The SBSGC designation indicates a C-filter configuration within this product family, focusing on single-stage attenuation capabilities for efficient noise reduction.

Replacement Considerations

SBSMC5000473MXT offers similar electrical characteristics but utilizes a larger 2220 package with higher current capacity. SBSGP5000473MXT provides Pi-filter topology in a 2012 package. Verify pinout compatibility and thermal management requirements before substituting these alternatives.
