Overview
The KEMET SCF19-040-0R8A1100J is a common mode filter from the SCF-J series, rated for 250V and 4A DC current. It features an inductance of 11 mH (11000 uH) with a maximum DC resistance of 70 mOhms. The component operates within a temperature range of -40°C to 120°C and utilizes a nanocrystalline metal core toroidal design.
Feature Summary
- Utilizes nanocrystalline metal core technology for ultra-high inductance and permeability
- Designed as a two-line common mode choke for effective noise suppression
- Constructed with a toroidal coil geometry for compact integration
Applications
- AC line filtering in electronic equipment
- Common mode noise reduction in power supply inputs
- EMI suppression in industrial control systems
Procurement Notes
Verify the complete part number including suffixes against official KEMET documentation to ensure correct specifications. Confirm that the required inductance value and current rating align with your circuit design requirements before procurement. Cross-reference datasheets to validate operating temperature ranges and physical dimensions for your specific mounting constraints.
Selection Notes
Select this component when high inductance values are required for common mode noise attenuation in AC line applications. The nanocrystalline core offers superior performance compared to traditional ferrite cores in certain frequency ranges. Ensure the 4A current rating meets the load requirements and that the through-hole mounting style fits the PCB layout.
Part Context
This component belongs to the KEMET SCF-J series of AC line filters. The series is characterized by toroidal coils with nanocrystalline metal cores, providing a wide variety of characteristics for common mode chokes. These filters are designed to handle significant inductance values while maintaining low DC resistance.
Replacement Considerations
Consult official KEMET resources for verified substitute part numbers within the SCF series. Ensure any replacement maintains equivalent inductance, current rating, and voltage specifications. Verify compatibility with existing mounting and thermal management designs.
