Common Mode Chokes datasheet and documents for CMF4-1004HLF
Common Mode Chokes Overview
The CMF4-1004HLF is a horizontal mount common mode choke manufactured by Gowanda Electronics. It features an inductance of 1,000 µH (1 mH) measured at 10 kHz and supports a maximum current rating of 5.7 A. The component exhibits a maximum DC resistance of 18 mΩ and withstands a voltage of 1.25 kVrms. Designed for through-hole mounting, it operates within a temperature range of -55°C to 125°C.
Common Mode Chokes Feature Summary
- Horizontal mounting configuration for space-constrained PCB layouts
- High current handling capability suitable for power line filtering
- Wide operating temperature range for harsh environments
Common Mode Chokes Applications
- Power supply input filtering
- EMI suppression in industrial equipment
- Noise reduction in aerospace systems
Common Mode Chokes Procurement Notes
Verify the specific suffix 'LF' indicates lead-free compliance against internal specifications. Confirm that the horizontal orientation matches the mechanical footprint requirements of the target assembly. Ensure the 5.7A current rating meets the peak load demands of the circuit design without saturation.
Common Mode Chokes Selection Notes
Select this component when a low-profile horizontal form factor is required for common mode noise suppression. The 18 mΩ DCR minimizes power loss in high-current applications. Verify that the 1.25 kVrms withstand voltage is sufficient for the isolation requirements of the specific power stage being protected.
Common Mode Chokes Part Context
Gowanda Electronics specializes in high-reliability magnetic components for defense and aerospace sectors. The CMF4 series represents their robust through-hole common mode chokes, engineered for stringent environmental standards including wide temperature tolerance and high surge current resilience.
Common Mode Chokes Replacement Considerations
The CMF4-1004HCLF is a listed variant within the same product family. Verify if lead-free certification is mandatory for the end application before substituting.
