SBSPP0250154MXT

Overview

The Knowles Syfer SBSPP0250154MXT is a surface-mount LC (Pi) EMI filter designed for low-pass applications. It features a third-order circuit topology with a single channel and a capacitance value of 0.15µF. The component supports a rated voltage of 25V and handles a continuous current of 1A. Housed in a 1206 (3216 Metric) package with three PCB pads, it measures 3.20mm x 1.65mm x 1.80mm. The device utilizes X7R dielectric material and provides an attenuation of 37dB at 100MHz.

Feature Summary

• Integrates a third-order LC Pi-filter topology for effective electromagnetic interference suppression
• Provides high current handling capability suitable for power line filtering applications
• Utilizes X7R ceramic dielectric technology for stable performance across operating temperatures

Applications

• General-purpose EMI/RFI filtering in electronic circuits
• Power supply input stages requiring noise reduction
• Signal integrity protection in compact surface-mount designs

Procurement Notes

Verify the specific suffix MXT corresponds to the required tape-and-reel packaging configuration before ordering. Confirm that the 25V rating and 1A current capacity align with the target circuit's maximum operational limits. Ensure the 1206 footprint matches the printed circuit board layout constraints. Check RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a compact, third-order low-pass filter is required for 25V DC lines carrying up to 1A. The 0.15µF capacitance offers a balance between size and filtering effectiveness. Consider the X7R temperature coefficient if the operating environment experiences significant thermal variations. The 1206 package allows for automated placement in standard SMD manufacturing processes.

Part Context

This part belongs to the SBSP series of surface-mount EMI filters from Knowles Syfer. The series focuses on providing integrated filtering solutions in small form factors. The SBSPP0250154MXT specifically addresses needs for moderate capacitance values in space-constrained applications where multiple discrete components would otherwise be required.

Replacement Considerations

No public confirmed substitute part numbers are available for direct replacement.
