SBSPP1000103MXB

Overview

The Knowles Syfer SBSPP1000103MXB is a surface-mount EMI filter circuit belonging to the SBSPP series. It features an LC (Pi) topology designed for low-pass filtering applications. The component has a capacitance of 1000 pF, a DC voltage rating of 100 V, and a current rating of 1 A. It is housed in a 1206 (3216 metric) package with three PCB pads. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates a third-order low-pass LC Pi filter network in a compact surface-mount footprint.
• Provides EMI/RFI suppression for single-channel signal lines without requiring external discrete components.
• Utilizes flexible termination technology to enhance mechanical reliability against board stress.

Applications

• General-purpose EMI suppression in electronic circuits
• Signal line filtering for data interfaces
• Power supply noise reduction in compact modules

Procurement Notes

Verify the complete part number including the suffix MXB to ensure correct packaging configuration. Confirm that the 1206 footprint matches the target PCB layout. Check RoHS compliance status if required by specific environmental regulations. Ensure the 1A current rating meets the operational requirements of the application circuit.

Selection Notes

Select this component when integrated EMI filtering is preferred over discrete LC networks to save board space. The 100V rating suits low-voltage signal and power lines. Consider the 1206 size constraints and the need for a third-order response. Verify compatibility with standard reflow soldering profiles for SMD components.

Part Context

This component is part of the Knowles Syfer SBSPP series, which offers pre-assembled passive filters. These devices consolidate multiple passive elements into a single package to improve consistency and reduce assembly complexity compared to using individual capacitors and inductors.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching electrical specifications such as capacitance, voltage rating, current handling, and physical footprint dimensions.
