SBSMP5000473MXT

Overview

The Knowles Syfer SBSMP5000473MXT is a surface-mount EMI filter circuit designed for high-frequency noise suppression. It features a Pi Filter topology with a capacitance of 0.047 µF and a DC voltage rating of 500 V. The component utilizes X7R dielectric material with a ±20% tolerance, ensuring stability across a temperature range of -55°C to +125°C. It provides an attenuation of 44 dB and supports a current rating of 10 A. The device is housed in a compact 6.6 mm x 5 mm package with a maximum height of 3.18 mm, suitable for automated surface mount assembly.

Feature Summary

• Integrates a Pi Filter topology within a single surface-mount package for efficient EMI suppression
• Utilizes X7R ceramic dielectric to maintain capacitance stability under varying thermal conditions
• Supports high continuous current loads up to 10 A for robust power line filtering applications

Applications

• High-density electronic assemblies requiring compact EMI filtering solutions
• Power supply input stages for noise attenuation in sensitive circuits
• Embedded systems operating in environments with significant electromagnetic interference

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm exact electrical characteristics and packaging configuration. Ensure that the selected variant matches the required attenuation and current ratings for the target application. Cross-reference datasheet specifications for mechanical dimensions to validate board layout compatibility before procurement.

Selection Notes

Select this component when space constraints necessitate a combined filtering solution rather than discrete components. The 500 V rating and 10 A current capacity make it suitable for moderate-power applications. Consider the 44 dB attenuation performance relative to the specific frequency spectrum of the noise being suppressed to ensure effective signal integrity protection.
