SBSGC5000472MXR

Overview

The Knowles Syfer SBSGC5000472MXR is a surface-mount feedthrough capacitor designed for high-frequency noise suppression. It features a capacitance of 4700 pF and a rated voltage of 500 VDC. The component utilizes X7R dielectric material with a ±20% tolerance, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) package, it supports a maximum current rating of 10 A. This Class 1/2 hybrid construction provides low impedance paths for EMI/RFI filtering in compact PCB layouts.

Feature Summary

• Integrated feedthrough architecture enables direct signal line grounding for effective common-mode noise attenuation.
• High current handling capability supports robust operation in power distribution and high-speed data lines.
• Compact surface-mount footprint facilitates automated assembly and dense board space utilization.

Applications

• EMI/RFI filtering in high-speed digital interfaces
• Power supply input/output decoupling
• Signal integrity protection in communication modules

Procurement Notes

Verify the specific suffix MXR against official datasheets to confirm packaging and terminal specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure storage conditions adhere to moisture sensitivity level requirements prior to reflow soldering.

Selection Notes

Select this component when high-current filtering is required within a small form factor. Compare against standard MLCCs if higher capacitance stability or lower ESL is needed. Verify that the 500V rating exceeds the peak circuit voltages and that the 10A current limit accommodates transient surges without thermal degradation.

Part Context

This part belongs to the SBSG series of high-reliability ceramic filters from Knowles Syfer. The series specializes in combining capacitive and inductive elements within single packages to provide superior attenuation compared to discrete components. It targets applications demanding stringent electromagnetic compatibility standards.

Replacement Considerations

Direct substitutes include other SBSG series feedthrough capacitors with matching 4700 pF capacitance and 500V ratings. Verify pinout compatibility and physical dimensions before replacing. Consult manufacturer cross-reference guides for equivalent parts with similar insertion loss characteristics.
