SBSPP0250104MXT

Overview

The Knowles Syfer SBSPP0250104MXT is a surface-mount EMI filter circuit designed for high-frequency noise suppression. It features a Pi-filter topology integrated into a single 1206 package. The component utilizes an X7R dielectric material with a capacitance of 0.1 µF and a tolerance of ±20%. It is rated for a DC voltage of 25 VDC and supports a current rating of 1 A. The device exhibits a DC resistance (DCR) of 0.5 Ω, ensuring low insertion loss in signal paths.

Feature Summary

• Integrates a complete Pi-filter network within a compact 1206 surface-mount footprint to minimize board space.
• Utilizes X7R ceramic dielectric technology to provide stable capacitance characteristics across operating temperatures.
• Engineered for high-current applications with a 1 A rating and low DC resistance for efficient signal transmission.

Applications

• High-speed data line filtering in consumer electronics
• EMI suppression in USB and HDMI interfaces
• Signal integrity protection in industrial control systems

Procurement Notes

Verify the specific suffix 'MXT' corresponds to the required reel packaging configuration during procurement. Confirm that the 1206 case size aligns with the target PCB land pattern dimensions. Ensure the 25 VDC rating meets the maximum operating voltage of the application circuit to prevent dielectric breakdown.

Selection Notes

Select this component when a discrete Pi-filter solution is required in a constrained 1206 area. The 0.1 µF capacitance value is suitable for decoupling and low-pass filtering applications. Consider the 0.5 Ω DCR impact on signal attenuation if used in high-impedance circuits. Verify compatibility with reflow soldering profiles compatible with X7R materials.

Part Context

This part belongs to the Knowles Syfer SBSPP series of integrated EMI filter circuits. These components consolidate multiple passive elements into a single package to reduce parasitic inductance and improve high-frequency performance compared to discrete implementations. The series targets applications requiring robust noise suppression in compact form factors.

Replacement Considerations

Direct substitutes must match the 1206 package, 0.1 µF capacitance, 25 VDC rating, and Pi-filter topology. Verify equivalent DCR and current ratings to ensure thermal and electrical compatibility. Cross-reference with other manufacturers offering integrated EMI filters in similar footprints.
