CMF64-7504SM

Common Mode Chokes Overview

The CMF64-7504SM is a surface mount common mode choke manufactured by Gowanda Electronics. It features an inductance of 7.5 mH measured at 10 kHz and supports a current rating of 440 mA. The component has a DC resistance (DCR) of 640 mOhm per winding. It utilizes a horizontal package with four PC pads for mounting.

Common Mode Chokes Feature Summary

• Surface mount construction for automated assembly
• Dual-line common mode filtering capability
• Horizontal footprint design

Common Mode Chokes Applications

• Signal line noise suppression
• Power supply EMI filtering
• Data bus protection

Common Mode Chokes Procurement Notes

Verify the specific suffix designation, as 'SMLF' variants exist within the same series. Confirm that the required inductance value matches the 7.5 mH specification exactly. Ensure the PCB layout accommodates the horizontal package dimensions and four-pad configuration to prevent mechanical stress during operation.

Common Mode Chokes Selection Notes

Select this component when high inductance is required for low-frequency noise attenuation on dual lines. The 440 mA current rating suits applications with moderate signal or power currents. Verify that the 640 mOhm DCR does not introduce excessive voltage drop in the target circuit path compared to lower inductance alternatives.

Common Mode Chokes Part Context

This part belongs to the CMF64 series of common mode transformers from Gowanda Electronics. The series offers various inductance values and current ratings. The CMF64-7504SM represents a high-inductance option within this surface mount family, distinguished by its specific 7.5 mH characteristic and 440 mA handling capacity.

Common Mode Chokes Replacement Considerations

Direct substitutes include CMF64-7504SMLF if the lead-free or specific termination variant is required. Other CMF64 models with similar inductance may serve as functional replacements if current ratings and physical dimensions are compatible.
