CMF2-7503SM

Common Mode Chokes Overview

The CMF2-7503SM is a surface mount common mode choke manufactured by Gowanda Electronics. It features an inductance of 750 µH measured at 10 kHz and supports a current rating of 1.5 A. The component has a DC resistance (DCR) of 150 mOhm. Designed for two-line applications, it utilizes a nonstandard package configuration suitable for space-constrained PCB layouts.

Common Mode Chokes Feature Summary

• Surface mount construction for automated assembly
• Two-line filtering capability for differential noise suppression
• High inductance value for effective common mode interference reduction

Common Mode Chokes Applications

• Data line filtering in electronic circuits
• EMI suppression in signal transmission lines
• Power supply input filtering

Common Mode Chokes Procurement Notes

Verify the exact physical dimensions and pinout configuration against the official Gowanda Electronics datasheet before integration, as the package is classified as nonstandard. Confirm that the 1.5 A current rating and 150 mOhm DCR meet the specific thermal and electrical requirements of the target application to ensure reliable operation under load conditions.

Common Mode Chokes Selection Notes

Select this component when high inductance is required for common mode noise attenuation in surface mount designs. The 750 µH value provides significant filtering performance compared to lower inductance alternatives. Ensure the 1.5 A current handling capacity aligns with the maximum operating current of the circuit to prevent saturation or excessive heating during normal operation.

Common Mode Chokes Part Context

This part belongs to the CMF2 series of common mode chokes from Gowanda Electronics. The series offers various inductance options tailored for different filtering needs. The CMF2-7503SM specifically addresses applications requiring higher inductance values while maintaining a compact surface mount footprint for modern electronics manufacturing.

Common Mode Chokes Replacement Considerations

Direct substitutes within the same series include CMF2-2503SM and CMF2-5003SM, which offer different inductance values but share similar form factors. Verify compatibility based on specific inductance requirements and current ratings before substitution.
