SBSMC0500474MXT

Overview

The Knowles Syfer SBSMC0500474MXT is a surface-mount EMI filter circuit designed for high-current applications. It features a capacitance of 0.47 µF with a ±20% tolerance and an X7R dielectric material. The component supports a DC voltage rating of 50 VDC and handles a continuous current of 20 A. It utilizes a 2220 (5750 Metric) package footprint with three PCB pads. The device operates within a temperature range of -55°C to +125°C and offers significant attenuation characteristics suitable for noise suppression.

Feature Summary

• Integrates feedthrough capacitor technology into a compact surface-mount form factor
• Provides effective electromagnetic interference suppression in low-pass configurations
• Supports high continuous current loads without compromising signal integrity

Applications

• Power supply input filtering for industrial electronics
• Noise suppression in automotive electronic control units
• EMI mitigation in telecommunications equipment power lines

Procurement Notes

Verify the specific suffix and packaging configuration against the manufacturer's latest datasheet before ordering. Confirm that the 2220 footprint matches your PCB layout requirements. Ensure the 20 A current rating aligns with your system's operational limits. Check for RoHS compliance status if required by your manufacturing standards. Validate lead-free specifications to meet environmental regulations.

Selection Notes

Select this component when high current handling is required alongside effective EMI filtering in a small footprint. Compare the 0.47 µF capacitance value against other series options like SBSMP or SFJE if different voltage ratings are needed. Consider the 2220 package size relative to available board space. Evaluate the 50 VDC rating against peak line voltages to ensure adequate margin. Assess thermal performance at maximum operating temperatures.

Part Context

This part belongs to the SBSMC series of EMI filter circuits from Knowles Syfer. These components combine feedthrough capacitor functionality with surface-mount convenience. The series is designed for applications requiring robust noise suppression in power distribution networks. It complements other Syfer products offering varying capacitance and voltage ratings.

Replacement Considerations

Direct substitutes include the SBSMC5000473MXT, which shares the same package but differs in capacitance and voltage rating. Verify electrical parameters carefully when cross-referencing with other SBSMC variants. No identical functional replacements exist with different pinouts.
