CMF3-2003SMLF

Common Mode Chokes Overview

The CMF3-2003SMLF is a surface mount common mode transformer choke manufactured by Gowanda Electronics. It provides 200 µH inductance at 1 kHz for two-line applications. The component features a low DC resistance of 14 mOhm and supports a maximum current rating of 7.2 A. Designed for horizontal mounting with four PC pads, it serves as an effective filter for suppressing electromagnetic interference in power circuits.

Common Mode Chokes Feature Summary

• Surface mount construction for automated assembly
• High current handling capability up to 7.2 A
• Low DC resistance for minimal power loss
• Two-line common mode filtering configuration

Common Mode Chokes Applications

• Power supply input filtering
• EMI suppression in AC/DC converters
• Noise reduction in industrial control systems

Common Mode Chokes Procurement Notes

Verify the specific suffix 'LF' indicates lead-free compliance against the manufacturer's latest datasheet. Confirm the package dimensions and pad layout match the PCB footprint requirements. Ensure the operating temperature range meets the system specifications. Check for RoHS certification status if required by regulatory standards.

Common Mode Chokes Selection Notes

Select this component when high current capacity is required alongside common mode noise suppression. The low DCR minimizes voltage drop and heat generation in high-power paths. Verify that the 200 µH value aligns with the target frequency response for the intended EMI filtering application.

Common Mode Chokes Part Context

This part belongs to the CMF3 series of surface mount common mode chokes from Gowanda Electronics. The series offers various inductance values and current ratings for different power levels. These components are designed for compact designs requiring robust EMI performance in space-constrained environments.

Common Mode Chokes Replacement Considerations

Check Gowanda's CMF3 series for alternative inductance or current ratings. Verify pinout compatibility before substituting with other manufacturers' common mode chokes. Ensure equivalent thermal and electrical performance characteristics.
