SBSPP1000222MXR

Overview

The Knowles Syfer SBSPP1000222MXR is a surface-mount LC (Pi) EMI filter circuit designed for high-frequency noise suppression. It features a third-order low-pass topology with a capacitance of 2200 pF, rated for 100 V DC and 1 A current. The component utilizes X7R dielectric material and is housed in a compact 1206 (3216 metric) package with three PCB terminals. This configuration provides effective attenuation for electromagnetic interference in signal lines.

Feature Summary

• Integrates a third-order LC Pi-filter network within a single surface-mount package to minimize board space.
• Provides robust electromagnetic interference attenuation using X7R ceramic dielectric characteristics.
• Supports continuous current handling up to 1 A while maintaining a 100 V DC voltage rating.

Applications

• Signal line filtering in portable electronic devices
• Noise suppression in automotive infotainment systems
• EMI mitigation in industrial control interfaces

Procurement Notes

Verify the specific suffix MXR against official datasheets to confirm packaging type and terminal finish. Ensure compatibility with automated pick-and-place equipment regarding the 1206 footprint dimensions. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a compact, high-current EMI solution is required for 100 V applications. The 1206 package offers a balance between thermal performance and spatial constraints. Verify that the X7R temperature coefficient meets the operational environment requirements compared to more stable C0G alternatives.

Part Context

This component belongs to the SBSPP series of EMI filter circuits from Knowles Syfer. The series is engineered for general-purpose noise suppression in modern electronics. It complements standard MLCC capacitors by providing integrated filtering functionality without requiring discrete component assembly.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative SMD Pi-filters only if they match the 1206 footprint, 100 V rating, and 1 A current capacity.
