SC-05-503

Common Mode Chokes Overview

The KEMET SC-05-503 is a two-line common mode filter designed for through-hole mounting. It features an inductance of 5 mH and a maximum DC resistance of 80 mΩ, with a rated current of 4 A. The component operates within a temperature range of -25°C to 105°C or 120°C depending on the specific datasheet version. Rated at 250 VAC, it utilizes ferrite core material and is packaged in a tubular form factor suitable for standard PCB assembly processes.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for two-line circuits
• Utilizes ferrite core construction for effective EMI/RFI filtering
• Supports high current handling capabilities up to 4 A

Common Mode Chokes Applications

• Mains power line filtering
• EMI/RFI suppression in AC power inputs
• General purpose data line filtering

Common Mode Chokes Procurement Notes

Verify the specific operating temperature rating (105°C vs 120°C) against the manufacturer's latest datasheet, as variations exist across documentation versions. Confirm that the 80 mΩ DC resistance and 5 mH inductance values align with your circuit requirements. Ensure the through-hole package dimensions fit your board layout constraints before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a robust, high-current common mode choke is required for AC mains applications. The 4 A rating makes it suitable for higher power loads compared to smaller signal chokes. Consider the physical size and axial/radial lead configuration compatibility with your assembly equipment. Verify insulation and safety certifications if used in direct mains-connected equipment.

Common Mode Chokes Part Context

This part belongs to KEMET's SC series of common mode coils, which are standard type filters designed for general electromagnetic interference suppression. The series offers various inductance values and current ratings to suit different power line requirements. These components are widely used in industrial and consumer electronics for compliance with emission standards.

Common Mode Chokes Replacement Considerations

SC-05-500 is a documented variant within the same SC series offering similar specifications. When substituting, verify that the inductance, current rating, and physical dimensions are compatible. Check for any differences in temperature ratings or certification approvals between the original and replacement parts.
