SBSGP5000332MXT

Overview

The Knowles Syfer SBSGP5000332MXT is a surface-mount EMI filter circuit rated for 500 VDC. It features a capacitance of 3300 pF with a tolerance of ±20% and utilizes X7R dielectric material. The component operates within a temperature range of -55°C to +125°C and supports a current rating of 5 A. Its physical dimensions are 5.25 mm in length, 3.2 mm in width, and 2.5 mm in height, conforming to the 1812 (4532 metric) package outline.

Feature Summary

• Integrates a Pi-filter topology for effective electromagnetic interference suppression
• Provides high attenuation performance suitable for sensitive signal lines
• Designed for direct surface-mount integration into compact PCB layouts

Applications

• High-speed data line protection in industrial equipment
• Signal filtering for automotive electronic control units
• EMI mitigation in telecommunications infrastructure

Procurement Notes

Verify that the specific SMD footprint matches the 1812 (4532 metric) dimensions during layout finalization. Confirm that the operating voltage does not exceed the 500 VDC rating under all transient conditions. Ensure thermal management accounts for the specified -55°C to +125°C operational window to maintain long-term reliability.

Selection Notes

Select this component when a dedicated low-pass filter structure is required rather than a single capacitor. The Pi-filter configuration offers superior noise rejection compared to standard MLCCs. Consider the 5 A current handling capability if the line carries significant load current alongside signal data.

Part Context

This part belongs to the Knowles Syfer EMI Network Filters series, specifically designed as LC or Pi filters. It differs from standard capacitors by integrating multiple reactive elements into a single surface-mount package to provide complex filtering characteristics without requiring discrete component assembly.

Replacement Considerations

Direct substitutes include other 1812 Pi-filter variants from the same manufacturer family with matching 500V ratings and similar capacitance values.
