SBSGP5000472MXT

Overview

The Knowles Syfer SBSGP5000472MXT is a surface-mount LC (Pi) EMI filter designed for high-frequency noise suppression. It features a capacitance of 4700 pF and a DC voltage rating of 500 V. The component utilizes X7R dielectric material with a tolerance of ±20%. Housed in an 1812 (4532 metric) package, it supports a current rating of 5 A and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates third-order low-pass filtering topology within a single compact surface-mount device
• Provides effective electromagnetic interference attenuation using LC Pi network architecture
• Engineered for high-voltage applications with robust 500 VDC rating capability

Applications

• General-purpose electromagnetic interference filtering in electronic circuits
• Power supply input stages requiring common-mode noise reduction
• Signal conditioning in systems sensitive to high-frequency disturbances

Procurement Notes

Verify the specific suffix MXT corresponds to the required tape-and-reel packaging configuration for automated assembly lines. Confirm that the 1812 footprint matches the target PCB land pattern dimensions precisely. Ensure the X7R dielectric characteristics align with the thermal stability requirements of the intended operating environment before finalizing procurement orders.

Selection Notes

Select this component when a single-device solution for third-order filtering is required to save board space compared to discrete implementations. Consider the 5 A current rating to ensure adequate headroom for the application's peak load conditions. Evaluate the X7R temperature coefficient against the system's operational thermal profile to guarantee consistent capacitance performance across the specified -55°C to +125°C range.

Part Context

This part belongs to the Knowles Syfer SBSG series of integrated EMI filters. These components consolidate multiple passive elements into a single package to simplify design and improve reliability. The series targets applications demanding efficient noise suppression in constrained spaces, offering a compact alternative to traditional discrete LC filter networks while maintaining high voltage handling capabilities.

Replacement Considerations

Direct substitutes include other SMD LC Pi filters from Knowles Syfer such as the SBSMP5000472MXT, which offers similar filtering characteristics but differs in physical package size and current rating specifications.
