Common Mode Chokes datasheet and documents for SCF20-05-1100
Common Mode Chokes Overview
The KEMET SCF20-05-1100 is a wire-wound common mode choke from the SCF series, designed for through-hole mounting. It features an inductance of 11 mH and supports a maximum DC current of 5 A. The component exhibits a maximum DC resistance of 39 mΩ and operates within a temperature range of -40°C to +120°C. Rated for 250 VAC, it utilizes a nanocrystalline core to provide high permeability and inductance for effective EMI suppression.
Common Mode Chokes Feature Summary
- Utilizes nanocrystalline metal core technology for ultra-high inductance and permeability
- Designed for three-phase power line applications with current compensation
- Through-hole termination style for robust PCB integration
Common Mode Chokes Applications
- Three-phase power supplies
- Industrial power conversion systems
- EMI filtering in AC input stages
Common Mode Chokes Procurement Notes
Verify the specific operating temperature rating against datasheet specifications, as sources indicate both -25°C and -40°C minimums. Confirm that the 11 mH inductance value aligns with circuit requirements. Ensure the 5 A current rating meets load demands. Check for RoHS compliance status before finalizing procurement orders.
Common Mode Chokes Selection Notes
Select this component when high inductance is required for three-phase noise suppression. The nanocrystalline core offers superior performance compared to standard ferrite cores. Ensure the PCB layout accommodates the through-hole package dimensions. Verify thermal management capabilities given the 120°C maximum operating temperature limit.
Common Mode Chokes Part Context
This part belongs to the KEMET SCF-X coil series, which specializes in toroidal coils with nanocrystalline metal cores. These components are engineered for passive components in power conversion systems, specifically targeting EMI filters and power factor correctors. The series provides design-in options for industrial automation and control applications requiring robust magnetic shielding.
Common Mode Chokes Replacement Considerations
Cross-reference with other SCF series variants for similar inductance values. Verify pin compatibility and physical footprint before substituting. Ensure replacement parts maintain the same nanocrystalline core characteristics for equivalent EMI performance.
