SBSGC5000473MXT

Overview

The Knowles Syfer SBSGC5000473MXT is a surface-mount EMI feedthrough capacitor designed for high-frequency noise suppression. It features a capacitance of 0.047 µF with a ±20% tolerance and an X7R dielectric, rated for 500 VDC. The component operates within a temperature range of -55°C to +125°C. Housed in a compact 2012 (5232 metric) package measuring 5.25 mm in length, 3.2 mm in width, and 2.5 mm in height, it provides 39 dB of attenuation. This device integrates filtering capabilities directly into the SMD footprint, eliminating the need for separate through-hole components.

Feature Summary

• Integrates EMI filtering functionality directly into a standard surface-mount footprint
• Provides significant signal attenuation for high-frequency interference suppression
• Supports operation across a wide industrial temperature range
• Utilizes robust X7R ceramic dielectric for stable capacitance performance

Applications

• High-density PCB layouts requiring integrated EMI suppression
• Power supply input stages for noise reduction
• Signal lines in sensitive electronic equipment
• Automotive electronics systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required termination styles and packaging formats. Confirm that the 2012 package dimensions align with the target PCB land pattern. Check for any recent product change notices or environmental compliance updates relevant to the manufacturing batch before finalizing procurement specifications.

Selection Notes

Select this component when space constraints prevent the use of traditional through-hole feedthrough capacitors. Ensure the circuit voltage does not exceed the 500 VDC rating and that the operating environment remains within the specified temperature limits. Consider the 39 dB attenuation requirement to verify sufficient noise reduction for the specific application frequency spectrum.

Part Context

This part belongs to the SBSG series of EMI filter circuits from Knowles Syfer. These components are engineered to replace discrete filter networks by combining capacitive elements with internal shielding structures. The series offers various capacitance values and package sizes to accommodate different filtering needs while maintaining a low profile suitable for modern miniaturized electronics.

Replacement Considerations

Direct substitutes include other SBSG series variants with similar capacitance and voltage ratings, such as the SBSGP5000473MXT, provided the package dimensions and attenuation characteristics meet the design requirements. Verify pinout compatibility and thermal performance before swapping.
