CMF4-1003HCLF

Common Mode Chokes Overview

The CMF4-1003HCLF is a horizontally mounted, epoxy-potted common mode choke manufactured by Gowanda Electronics. It features a dual-line configuration with a nominal inductance of 100 µH measured at 10 kHz. The component supports a maximum current rating of 12 A and exhibits a low DC resistance (DCR) of 4 mΩ. Designed for through-hole installation, it utilizes a four-pin PC mount package. The device is RoHS compliant and constructed to withstand rigorous environmental conditions typical of aerospace and defense applications.

Common Mode Chokes Procurement Notes

Verify the specific termination type when ordering, as Gowanda distinguishes between leaded and lead-free variants using suffixes such as LF. Confirm that the horizontal mounting orientation aligns with your PCB layout constraints. Ensure the 12 A current rating meets your system's peak load requirements without exceeding thermal limits defined in the official datasheet.

Common Mode Chokes Selection Notes

Select this component when high current capacity and robust mechanical protection are required in a compact form factor. The horizontal profile suits applications where vertical height is restricted but board space allows for lateral placement. Compare its 4 mΩ DCR against alternatives to minimize power loss in high-current paths.
