SCR38-350-1R8B008JH

Overview

The KEMET SCR38-350-1R8B008JH is a common mode choke from the large SCR series, designed for high-current applications. It features an inductance of 850 µH and supports a nominal DC current of 35 A. The component has a maximum DC resistance (DCR) of 2.5 mΩ and is rated for 250 V. It utilizes a radial lead package and operates within a temperature range starting from -40°C.

Feature Summary

• Provides effective common mode noise filtering with high inductance characteristics
• Capable of handling high continuous DC currents up to 35 A
• Constructed with low DC resistance to minimize power loss

Applications

• Three-phase power line filtering
• Industrial motor drive input stages
• High-power supply EMI suppression

Procurement Notes

Verify the exact datasheet specifications directly from KEMET or authorized distributors before integration. Confirm that the 2.5 mΩ DCR and 35 A current ratings align with your thermal management design. Ensure the radial lead configuration fits your PCB layout constraints. Cross-reference the voltage rating against your system's peak operating conditions to guarantee reliability under all load scenarios.

Selection Notes

Select this component when high current capacity and significant common mode attenuation are required in a single-phase or three-phase context. The low DCR makes it suitable for efficiency-sensitive power stages. Consider the physical size and lead type during mechanical design. Compare performance against standard toroidal chokes if space is limited, noting that this unit offers robust current handling capabilities.

Part Context

This part belongs to KEMET's large SCR series of common mode chokes. These components are engineered for demanding industrial and power electronics environments. The series emphasizes high permeability cores and stable inductance under heavy load conditions, distinguishing them from smaller signal-grade filters.

Replacement Considerations

Check for direct substitutes within the SCR38 family with matching 850 µH and 35 A ratings. Verify pinout compatibility for radial leads. Ensure alternative parts meet the same -40°C minimum operating temperature and 250 V rating requirements.
