CMF16-473700-B

Common Mode Chokes Overview

The CMF16-473700-B is a two-line common mode choke manufactured by Triad Magnetics, designed for through-hole mounting. It features an inductance of 47 mH at 10 kHz with a maximum DC current rating of 700 mA and a DC resistance of 1.39 Ohms. The component operates within a temperature range of -40°C to +105°C and utilizes radial leads with a diameter of 0.7 mm.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for two-line circuits
• Supports through-hole PCB mounting via radial leads
• Operates reliably across extended industrial temperature ranges

Common Mode Chokes Applications

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

Common Mode Chokes Procurement Notes

Verify the specific suffix '-B' indicates bulk packaging configuration when sourcing. Confirm that the 47 mH inductance value corresponds to the 10 kHz test frequency specified in official documentation. Ensure the 700 mA current rating meets the application's continuous DC requirements before integration.

Common Mode Chokes Selection Notes

Select this component for applications requiring 47 mH common mode impedance at 10 kHz. The 700 mA current rating suits moderate power lines. Verify that the 1.39 Ohm DC resistance does not cause excessive voltage drop. Ensure the through-hole form factor fits the target PCB layout constraints.

Common Mode Chokes Part Context

This part belongs to the CMF series of common mode chokes from Triad Magnetics. It is distinct from the CMF16K kit, which contains multiple values. The CMF16-473700-B is a single discrete component focused on a specific 47 mH specification for targeted EMI filtering tasks.

Common Mode Chokes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-referencing requires matching 47 mH inductance, 700 mA current, and through-hole package dimensions.
