SC-30-050H

Overview

The KEMET SC-30-050H is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 0.5 mH and supports a continuous current rating of 30 A with a low DC resistance of 3 mΩ. The component operates within a temperature range of -40°C to +105°C and withstands an AC voltage of 250 V. Its physical dimensions are 55.00 mm in diameter and 30.00 mm in maximum height, utilizing a radial leaded package suitable for robust industrial environments.

Feature Summary

• Provides effective common mode noise suppression for AC power lines
• Capable of handling high continuous current loads up to 30 A
• Constructed with low DC resistance to minimize power loss
• Designed for through-hole mounting on printed circuit boards

Applications

• AC line input filtering in industrial power supplies
• Noise suppression in motor drive systems
• Electromagnetic interference (EMI) reduction in heavy machinery
• Power conditioning units requiring high current capacity

Procurement Notes

Verify the specific manufacturer datasheet for detailed thermal derating curves and mechanical drawing tolerances before finalizing the design. Confirm that the through-hole footprint matches the target PCB layout constraints. Ensure the operating environment remains within the specified -40°C to +105°C range to maintain performance integrity and longevity of the component.

Selection Notes

Select this component when high current handling capability is required alongside significant common mode noise attenuation. The 0.5 mH inductance value offers a balance between impedance at switching frequencies and minimal impact on fundamental power flow. Consider the physical size constraints due to the 55 mm diameter housing when designing the enclosure or chassis layout.

Part Context

This part belongs to KEMET's SC series of common mode chokes, which are engineered for demanding power electronics applications. The series is characterized by high saturation currents and stable inductance characteristics under load. These components are widely used in sectors requiring reliable EMI compliance and robust electrical isolation in AC power circuits.

Replacement Considerations

Check for direct substitutes such as the UALSC30050H000 alias if sourcing flexibility is needed. Ensure any replacement maintains the 0.5 mH inductance, 30 A current rating, and compatible physical dimensions for the existing through-hole mounting structure.
