SBSPP0500473MXT

Overview

The Knowles Syfer SBSPP0500473MXT is a surface-mount LC Pi filter designed for EMI suppression. It features a capacitance of 0.047 µF with a ±20% tolerance and an X7R dielectric. The component is rated for 50 V DC and supports a continuous current of 1 A. Housed in a compact 1206 (3216 metric) package with three PCB pads, it measures 3.20 mm x 1.60 mm x 1.80 mm. The device provides 37 dB attenuation at 100 MHz and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates LC Pi topology for effective low-pass filtering in a single SMD package
• Provides high attenuation performance for EMI/RFI noise suppression
• Utilizes flexible soft terminations to enhance solder joint reliability under thermal stress

Applications

• General-purpose EMI filtering in electronic circuits
• Power line noise suppression in portable devices
• Signal integrity protection in consumer electronics

Procurement Notes

Verify the specific suffix 'MXT' corresponds to the tape and reel packaging configuration required for your assembly process. Confirm that the 50V rating and 1A current limit align with your circuit's maximum operating conditions. Ensure the 1206 footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require integrated EMI filtering without discrete components. The 1206 package offers a balance between filtration capability and board area. Consider the X7R dielectric stability for applications experiencing moderate temperature variations. Verify that the 1A current handling meets the load requirements of the protected circuit branch.

Part Context

This part belongs to the SBSPP series of EMI filter circuits from Knowles Syfer. The series specializes in compact, surface-mount solutions for noise suppression. These filters combine capacitive and inductive elements to provide third-order low-pass characteristics. The product line targets modern electronics requiring efficient electromagnetic interference management in small form factors.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative 1206 LC Pi filters with matching 50V ratings and similar capacitance values if direct replacement is necessary.
