SBSGP5000222MXT

Overview

The Knowles Syfer SBSGP5000222MXT is a surface-mount LC (Pi) EMI filter circuit designed for high-frequency noise suppression. It features a capacitance of 2200 pF with a tolerance of ±20% and utilizes X7R dielectric material. The component is rated for a DC voltage of 500 V and supports a continuous current of 5 A. Housed in an 1812 (4532 metric) package with three printed circuit board pads, it measures 4.55 mm in length, 3.20 mm in width, and 2.64 mm in height. The device provides an attenuation value of 39 dB at 100 MHz.

Feature Summary

• Integrates LC Pi-filter topology for third-order low-pass signal conditioning within a compact surface-mount footprint.
• Provides significant electromagnetic interference attenuation at 100 MHz to protect sensitive circuits from high-frequency noise.
• Utilizes robust X7R ceramic dielectric to maintain stable electrical performance across the specified industrial temperature range.

Applications

• High-speed digital interface protection
• Power line filtering in communication equipment
• Noise suppression in automotive electronics

Procurement Notes

Verify the complete part number including the suffix MXT to ensure correct reel packaging configuration. Confirm that the 1812 package dimensions align with the target PCB land pattern. Check RoHS compliance status against specific regional regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a dedicated low-pass filter structure is required rather than a single capacitor. The 500V rating and 5A current capacity suit moderate power applications. Ensure the 39 dB attenuation at 100 MHz meets the system's specific EMI reduction targets compared to standard MLCC alternatives.

Part Context

This component belongs to the SBSG series of EMI filter circuits manufactured by Knowles Syfer. The series specializes in integrated passive devices that combine multiple components into a single surface-mount package to save board space and improve reliability in dense electronic assemblies.

Replacement Considerations

Direct substitutes require matching the 1812 package, 500V rating, 2200pF capacitance, and LC Pi-filter topology. Verify that any alternative offers comparable 39 dB attenuation at 100 MHz and identical thermal characteristics.
