- AEC-Q200 qualified for reliability in automotive grade single-phase power line applications.
- Designed for high voltage isolation capabilities suitable for on-board chargers and medium power drives.
Applications
- High Voltage Automotive and Harsh Environment Industrial EMI Filtering
- On Board Charger for EV/PHEV
- Medium Power Drives
Procurement Notes
Verify the specific part number against official KEMET documentation to ensure accuracy, as similar series parts like SCF39XV may have different inductance values. Confirm that the 210 µH specification matches the design requirements, distinguishing it from other variants in the SCF or SCT families. Ensure the through-hole package and pin configuration align with the target PCB layout before finalizing procurement.
Selection Notes
Select this component when high current handling (42 A) and robust EMI suppression are required for single-phase AC lines. The nanocrystalline core offers superior performance compared to standard ferrite cores in specific frequency ranges. Consider the wide operating temperature range (-40°C to +150°C) for demanding thermal environments. Verify that the through-hole mounting style is compatible with the assembly process.
Part Context
This component belongs to the KEMET SCF-XV series of high permeability ferrite toroidal coils. These components are engineered specifically for automotive and harsh environment industrial applications. The series provides various characteristics to meet diverse EMI filtering needs, with this specific model focusing on single-phase applications requiring high current capacity and voltage ratings.
Replacement Considerations
The SCF39XV-420-2R4B004JH shares the same physical footprint but differs in inductance (400 µH vs 210 µH). The SCT39XV-420-2R4B004JH also varies significantly in inductance (119 µH). Direct substitution requires verifying that the lower inductance of the SCR39XV does not compromise filter performance in the specific circuit application.
