SBSMP5000333MXT

Overview

The Knowles Syfer SBSMP5000333MXT is a surface-mount EMI filter circuit featuring a Pi (LC) topology. It provides a capacitance of 0.033 µF with a tolerance of ±20% and utilizes an X7R dielectric material. The component is rated for a DC voltage of 500 V and supports a continuous current of 1 A. Designed for high-frequency noise suppression, it offers an attenuation of 44 dB at 100 MHz. The device is housed in a compact 1206 (3216 metric) package with three PCB pads, suitable for space-constrained applications requiring effective signal integrity protection.

Feature Summary

• Integrates a Pi-filter network topology to provide multi-stage low-pass filtering characteristics within a single surface-mount component.
• Utilizes X7R ceramic dielectric technology to maintain stable electrical performance across the specified operating temperature range.
• Features a compact three-pad footprint design that facilitates efficient board layout while delivering significant high-frequency attenuation.

Applications

• High-speed digital signal line protection
• Power supply input filtering
• RFI/EMI suppression in communication modules

Procurement Notes

Verify the specific suffix MXT corresponds to the reel packaging configuration required for your assembly process. Confirm that the 1 A current rating and 500 V DC withstand capability align with your system's maximum operational limits. Ensure the 1206 footprint dimensions match your established PCB land pattern to guarantee proper solder joint reliability during manufacturing.

Selection Notes

Select this component when a dedicated Pi-filter structure is preferred over discrete LC components to save board space. The 500 V rating makes it suitable for higher voltage domains compared to standard low-voltage filters. Consider the 44 dB attenuation specification against your specific noise spectrum requirements to ensure adequate interference reduction without compromising signal integrity.

Part Context

This part belongs to the SBSMP series of EMI filter circuits from Knowles Syfer. The series specializes in integrated passive networks designed for surface-mount assembly. These components consolidate multiple filtering elements into a single package, simplifying the bill of materials and reducing the complexity of high-density electronic designs requiring robust noise suppression.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by matching the 1206 footprint, 0.033 µF capacitance, and 500 V rating before considering alternative sources.
