SCR38B-350-1R8B008JH-BK

Overview

The KEMET SCR38B-350-1R8B008JH-BK is a radial leaded common mode choke designed for high-current applications. It features a rated current of 35A and an inductance of 850uH (0.85mH). The component supports a voltage rating of 500V and exhibits a DC resistance (DCR) of 2.7mOhms. Constructed with proprietary S15H ferrite material, it offers high permeability and impedance while maintaining a space-saving form factor.

Feature Summary

• Utilizes proprietary S15H ferrite material for high permeability and impedance characteristics
• Space-saving design enabled by high permeability core material
• Radial leaded construction for through-hole mounting

Applications

• Common mode noise filtering in power supply circuits
• EMI suppression in high-current AC/DC conversion systems
• Electromagnetic interference reduction in industrial power equipment

Procurement Notes

Verify the complete part number including suffixes such as -BK to ensure correct packaging and compliance specifications. Confirm that the 35A current rating and 850uH inductance align with your circuit requirements. Check for UL 94 V-0 flammability ratings if safety certification is mandatory for your application environment.

Selection Notes

Select this component when high current handling capacity of 35A is required alongside significant common mode noise attenuation. The low DCR of 2.7mOhms minimizes power loss compared to higher resistance alternatives. Ensure the 500V voltage rating exceeds the maximum operating voltage of your system to maintain reliability and safety margins.

Part Context

This component belongs to the KEMET SCR series of common mode chokes, which are toroidal coils engineered for robust performance. The series utilizes specialized ferrite materials to achieve high impedance in compact packages, making them suitable for dense electronic assemblies requiring effective EMI management.

Replacement Considerations

Cross-reference with other KEMET SCR38B variants or equivalent high-current common mode chokes from manufacturers like TDK or Murata. Ensure substitute parts match the 35A current rating, 850uH inductance, and radial lead configuration to maintain mechanical and electrical compatibility.
