SBSGP5000333MXT

Overview

The Knowles Syfer SBSGP5000333MXT is a surface-mount EMI filter circuit featuring X7R dielectric technology. It provides a capacitance of 33 nF with a tolerance of ±20% and operates at a DC voltage rating of 500 VDC. The component utilizes a 2R1 configuration, functioning as a C-filter or PI filter structure for effective noise suppression. Designed for robust performance, it supports an operating temperature range from -55°C to +125°C. The device is supplied in reel packaging, suitable for automated surface mount assembly processes.

Feature Summary

• Integrated EMI filter circuit architecture combining capacitive filtering stages
• High-voltage insulation capability rated for 500 VDC applications
• Stable X7R ceramic dielectric ensures consistent performance across wide temperature variations
• Surface-mount design facilitates compact PCB integration

Applications

• Electromagnetic interference suppression in high-voltage power lines
• Signal conditioning in industrial control systems
• Noise filtering in automotive electronic modules

Procurement Notes

Verify the specific package type and termination finish against the official datasheet before integration. Confirm that the 500V DC rating aligns with peak system voltages. Ensure the reel quantity matches production requirements. Check for any specific handling instructions regarding moisture sensitivity levels during storage and reflow soldering processes.

Selection Notes

Select this component when a combined filtering solution is required rather than discrete capacitors. The 33 nF value offers significant attenuation for specific frequency bands. Consider the physical footprint constraints of the surface-mount package. Evaluate the thermal stability provided by the X7R material for environments subject to temperature fluctuations.

Part Context

This part belongs to the SBSGP series of surface-mount EMI filters from Knowles Syfer. These components are engineered to replace multiple discrete passive elements, reducing board space and improving reliability. The series is designed for demanding applications requiring high voltage isolation and effective common-mode or differential-mode noise reduction.

Replacement Considerations

Direct substitutes must match the 33 nF capacitance, 500V rating, and 2R1/PI filter topology. Verify equivalent thermal ratings and physical dimensions to ensure compatibility with existing footprints.
