CMF16-473700

Common Mode Chokes Overview

The Triad Magnetics CMF16-473700 is a through-hole common mode choke designed for noise suppression in two-line circuits. It features an inductance of 47 mH at 1 kHz with a tolerance of +30%/-50%. The component supports a maximum DC current of 0.7 A and has a maximum DC resistance of 1.39 Ohms. It operates within a temperature range of -40°C to +105°C.

Common Mode Chokes Feature Summary

• Provides common mode noise filtering for two-line configurations
• Utilizes through-hole termination for board mounting
• Engineered for operation across extended industrial temperature ranges

Common Mode Chokes Applications

• Power supply input filtering
• Signal line noise suppression
• EMI reduction in electronic equipment

Common Mode Chokes Procurement Notes

Verify the specific suffix designation, as variants such as CMF16-473700-B may exist with identical core specifications but different packaging or marking. Confirm that the required inductance tolerance (+30%/-50%) aligns with circuit design constraints before ordering. Ensure the 0.7 A current rating meets the application's peak load requirements.

Common Mode Chokes Selection Notes

Select this component when a 47 mH common mode inductor is required for low-current applications up to 0.7 A. The wide inductance tolerance allows for cost-effective sourcing where precise values are not critical. Verify that the physical footprint and lead diameter are compatible with the target PCB layout and assembly process.

Common Mode Chokes Part Context

This part belongs to the CMF series of common mode chokes from Triad Magnetics. The series offers various inductance values and current ratings for general-purpose EMI filtering. The CMF16-473700 specifically targets applications requiring moderate inductance with standard through-hole mounting capabilities.

Common Mode Chokes Replacement Considerations

Direct substitutes include other Triad Magnetics parts within the CMF16 series with matching 47 mH inductance and 0.7 A current ratings. Cross-brand replacements must match the 47 mH value, 0.7 A saturation current, and through-hole package dimensions to ensure functional compatibility.
