SC-05-D030

Common Mode Chokes Overview

The KEMET SC-05-D030 is a through-hole common mode filter designed for power line noise suppression. It features an inductance of 30 µH measured at 100 kHz and supports a maximum DC current of 5 A. The component has a maximum DC resistance of 20 mΩ and operates within a temperature range of -40 °C to +105 °C. Rated for 250 VAC, it utilizes a single-channel architecture with axial leads for PCB mounting.

Common Mode Chokes Feature Summary

• Provides effective attenuation of electromagnetic interference on AC power lines
• Supports high continuous current loads up to 5 A without saturation
• Features low impedance construction to minimize voltage drop across the circuit

Common Mode Chokes Applications

• Input filtering for switching mode power supplies
• EMI suppression in consumer electronic devices
• Noise reduction in industrial control equipment

Common Mode Chokes Procurement Notes

Verify that the specific order matches the SC-05-D030 designation rather than variants like SC-05-D030J which may differ in tolerance or packaging. Confirm lead times and availability directly with authorized distributors as supply levels fluctuate. Ensure the purchasing documentation explicitly states the 5A rating and 30µH inductance to avoid receiving lower-specification alternatives.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring robust common mode noise rejection for 5A power rails. The through-hole package offers mechanical stability suitable for applications subject to vibration. Engineers should verify that the 20 mΩ DCR meets the system's efficiency requirements and that the 250VAC rating aligns with the local mains voltage standards.

Common Mode Chokes Part Context

This part belongs to the SC series of common mode chokes from KEMET. These components are engineered for general-purpose EMI filtering in AC power applications. The series provides reliable performance for suppressing conducted emissions generated by switching power electronics and other noisy loads.

Common Mode Chokes Replacement Considerations

The SC-05-D030J is a related variant within the same family. Verify if the J suffix indicates a specific tolerance or packaging difference before substitution. Cross-reference electrical parameters such as inductance and current rating to ensure functional equivalence.
