CMF3-2003SM

Common Mode Chokes Overview

The CMF3-2003SM is a surface mount common mode choke manufactured by Gowanda Electronics. It features an inductance of 200 µH measured at 1 kHz and supports a maximum current rating of 7.2 A. The component exhibits a low DC resistance (DCR) of 14 mOhm, ensuring minimal power loss in high-current applications. Designed for horizontal mounting on four PCB pads, this device provides effective electromagnetic interference suppression for differential signal lines.

Common Mode Chokes Feature Summary

• Surface mount configuration for automated assembly
• High current handling capability up to 7.2 A
• Low DC resistance for efficient power transmission
• Common mode noise filtering for data lines

Common Mode Chokes Applications

• Data line filtering
• Power supply EMI suppression
• Industrial control systems
• USB interface protection

Common Mode Chokes Procurement Notes

Verify the specific suffix 'SM' confirms the surface mount package variant. Confirm RoHS compliance status if lead-free requirements are mandatory for your assembly process. Cross-reference the 7.2 A current rating against your system's peak load conditions to ensure adequate margin. Check the 14 mOhm DCR specification against thermal management constraints.

Common Mode Chokes Selection Notes

Select this component when high current capacity is required alongside common mode noise reduction. The 200 µH value targets specific frequency attenuation needs. Compare the 7.2 A rating against alternative models like the CMF3-1003SM if lower inductance suffices. Ensure the surface mount footprint matches your PCB layout constraints.

Common Mode Chokes Part Context

This part belongs to the CMF3 series of common mode transformers from Gowanda Electronics. The series offers various inductance values and current ratings tailored for different filtering requirements. The CMF3-2003SM specifically addresses mid-range inductance needs with high current tolerance, fitting into the broader portfolio of magnetic components designed for robust electronic environments.

Common Mode Chokes Replacement Considerations

The CMF3-1003SM serves as a related variant within the same series but offers 100 µH inductance. Verify if the reduced inductance meets your filtering specifications. No direct cross-manufacturer substitutes are confirmed in public documentation; consult Gowanda engineering for equivalent performance alternatives.
