SBSPP0500683MXT

Overview

The Knowles Syfer SBSPP0500683MXT is a surface-mount LC (Pi) EMI filter designed for low-pass applications. It features a capacitance of 0.068µF and a rated voltage of 50V, with a current rating of 1A. The component utilizes X7R dielectric technology and is housed in a 1206 (3216 metric) package measuring 3.20mm x 1.60mm x 1.80mm. It provides third-order filtering with an attenuation value of 37dB at 100MHz. The device operates within a temperature range of -55°C to +125°C and meets RoHS3 standards.

Feature Summary

• Third-order LC Pi topology for enhanced high-frequency noise suppression
• Compact 1206 surface-mount footprint for space-constrained designs
• X7R ceramic dielectric ensuring stable performance across wide temperature ranges

Applications

• General-purpose EMI/RFI filtering in electronic circuits
• Power line noise suppression in consumer electronics
• Signal integrity protection in communication modules

Procurement Notes

Verify the specific ordering suffix MXT corresponds to the required tape and reel packaging configuration before procurement. Confirm that the 50V DC rating aligns with the maximum operating voltage of the target circuit to prevent derating issues. Ensure compatibility with standard reflow soldering profiles for 1206 packages during assembly planning.

Selection Notes

Select this component when a compact, third-order low-pass filter is required for 50V systems. The 0.068µF capacitance offers a balance between size and filtering capability. Consider the 1A current rating to ensure it exceeds the maximum load current of the application without thermal degradation.

Part Context

This part belongs to the SBSP series of EMI filters from Knowles Syfer. The series focuses on providing reliable noise suppression solutions in small form factors suitable for modern surface-mount assembly processes. The SBSPP variant specifically denotes the LC Pi filter configuration within this product line.

Replacement Considerations

Direct substitutes must match the 1206 package, 0.068µF capacitance, 50V rating, and LC Pi topology. Verify pinout compatibility and electrical characteristics such as attenuation curves and current ratings before substitution.
