SC-35-SD040J

Overview

The KEMET SC-35-SD040J is a three-phase common mode choke designed for power line filtering applications. It features an inductance of 40 µH at 100 kHz and supports a maximum DC current of 35 A with a low DC resistance of 2 mΩ. Rated for 250 V AC/DC, this component utilizes through-hole mounting with six vertical pins. It operates within a temperature range of -40°C to +120°C and complies with RoHS3 standards.

Feature Summary

• Provides effective common mode noise suppression for three-phase power lines
• Engineered for high current handling capabilities up to 35 A
• Features low DC resistance to minimize power loss and heat generation
• Constructed with robust materials suitable for demanding industrial environments

Applications

• Three-phase power line filtering in industrial machinery
• Noise suppression in variable frequency drives (VFDs)
• Electromagnetic interference reduction in motor control systems
• Power quality improvement in renewable energy inverters

Procurement Notes

Verify the specific suffix J against official KEMET documentation to confirm pin configuration and tolerance specifications. Ensure compatibility with existing PCB layouts regarding the six-pin vertical through-hole footprint. Cross-reference thermal management requirements given the 35 A rating and operating temperature limits. Confirm RoHS3 compliance status if required by your manufacturing standards.

Selection Notes

Select this component when three-phase common mode filtering is required for currents up to 35 A. The 40 µH inductance value is suitable for standard switching frequencies around 100 kHz. Consider the 2 mΩ DCR for efficiency calculations in high-power circuits. The wide temperature range makes it appropriate for harsh industrial settings where ambient temperatures may fluctuate significantly.

Part Context

This part belongs to the SC-J series of common mode chokes from KEMET. The series is characterized by high current capacity and low impedance characteristics. These components are widely used in power electronics to mitigate electromagnetic interference. The SC-35 designation indicates the specific form factor and pin arrangement within the product family.

Replacement Considerations

Consult official KEMET substitution guides for verified alternatives. Ensure any replacement matches the 40 µH inductance, 35 A current rating, and 250 V voltage rating. Verify that the physical footprint and pinout remain compatible with the existing design.
