SCR38B-200-2R3A010JH

Overview

The KEMET SCR38B-200-2R3A010JH is a three-phase common mode choke designed for industrial power line filtering. It features a nanocrystalline metal core and offers an inductance of 1 mH at 10 kHz with a DC current rating of 20 A. The component has a maximum voltage rating of 500 V and a typical DC resistance (DCR) of 3.4 to 3.5 mOhms. It operates within a temperature range of -40°C to +120°C and utilizes a through-hole mounting style.

Feature Summary

• Utilizes nanocrystalline metal ring cores for high permeability and inductance
• Designed for three-phase AC line filtering applications
• Supports high continuous DC current ratings up to 20 A

Applications

• Industrial power line filtering
• Three-phase motor drive systems
• Power quality improvement equipment

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest datasheet to confirm mechanical dimensions and terminal configurations, as suffixes often denote critical physical variations. Ensure the required operating temperature range aligns with the specified -40°C to +120°C limit. Confirm that the 20 A current rating meets the system's continuous load requirements without exceeding thermal limits.

Selection Notes

Select this component when high inductance is required for three-phase noise suppression in industrial environments. The nanocrystalline core provides superior performance compared to standard ferrite cores for low-frequency applications. Ensure the PCB or panel layout accommodates the through-hole terminals and the physical size of the ring core assembly. Verify that the 500 V rating exceeds the peak line-to-line voltages present in the application.

Part Context

This part belongs to the KEMET SCR38 series of AC line filters. The series is characterized by the use of nanocrystalline materials to achieve ultrahigh inductance values. These components are engineered specifically for robust electromagnetic interference (EMI) suppression in demanding industrial power electronics contexts where standard chokes may saturate.

Replacement Considerations

Cross-reference with other KEMET SCR38 variants if different current or inductance values are needed. Verify that any substitute maintains the three-phase configuration and nanocrystalline core technology to ensure equivalent EMI suppression performance.
