SBSGP5000472MXR

Overview

The Knowles Syfer SBSGP5000472MXR is a surface-mount LC (Pi) EMI filter designed for high-frequency noise suppression. It features a third-order low-pass configuration with a capacitance of 4700 pF and a rated voltage of 500 VDC. The component utilizes X7R dielectric material, offering a tolerance of ±20%. Housed in an 1812 (4532 metric) package with three printed circuit board pads, it supports a current rating of 5 A. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates a third-order LC Pi-filter topology for effective electromagnetic interference attenuation
• Provides high-voltage handling capability suitable for demanding power line applications
• Utilizes X7R ceramic dielectric for stable performance across specified operating temperatures

Applications

• General-purpose EMI/RFI filtering in electronic circuits
• Power supply input stages requiring noise suppression
• Signal conditioning where low-pass filtering is required

Procurement Notes

Verify the specific suffix MXR against official datasheets to confirm package dimensions and termination specifications. Ensure compatibility with PCB footprint requirements for the 1812 (4532 metric) form factor. Confirm that the 500 VDC rating and 5 A current capacity align with system design constraints before integration.

Selection Notes

Select this component when a compact, surface-mount solution is needed for third-order low-pass filtering. The 1812 package offers a balance between size and power handling. Consider the X7R dielectric characteristics for temperature stability. Verify that the 4700 pF capacitance meets the specific cutoff frequency requirements of the target application.

Part Context

This part belongs to the Knowles Syfer SBSG series of integrated EMI filters. These components combine passive elements into a single surface-mount package to simplify assembly and reduce board space. The series targets applications requiring robust noise suppression in compact form factors.

Replacement Considerations
