It features a single-channel configuration with an inductance of 39 mH at 1 kHz, exhibiting a tolerance of -30% to +50%. The component supports a maximum DC current of 800 mA and has a maximum DC resistance of 1.21 ohms. It operates within a temperature range of -40°C to +105°C and measures 24.5 mm in length.

Common Mode Chokes Feature Summary

• Radial leaded construction for reliable through-hole printed circuit board integration
• Dual-line filtering capability for effective common mode noise suppression
• Robust thermal performance suitable for high-temperature operational environments

Common Mode Chokes Applications

• Power supply input filtering stages
• Signal line noise reduction in electronic equipment
• Electromagnetic interference suppression circuits

Common Mode Chokes Procurement Notes

Verify the specific suffix designation during procurement, as it indicates bulk packaging rather than a functional change. Confirm that the required inductance tolerance aligns with the specified -30% to +50% range for your design. Ensure the physical dimensions and lead spacing match your PCB footprint requirements before finalizing orders.

Common Mode Chokes Selection Notes

Select this component when a 39 mH inductance value is required for common mode noise attenuation. The 800 mA current rating must accommodate the maximum expected DC load without saturation. Verify that the 1.21 ohm DC resistance does not introduce excessive voltage drop in the application circuit. Ensure the operating environment stays within the -40°C to +105°C temperature limits.

Common Mode Chokes Part Context

This part belongs to the Triad Magnetics CMF series of common mode chokes. The series offers various inductance values tailored for different filtering needs. The CMF16-393800-B specifically provides a mid-range inductance value suitable for general-purpose noise suppression applications requiring moderate current handling capabilities.

Common Mode Chokes Replacement Considerations

Direct substitutes include other Triad Magnetics CMF16 series parts with similar electrical characteristics. Cross-brand replacements require matching inductance, current rating, and physical package dimensions. Verify compatibility with existing PCB layouts and thermal management strategies when considering alternative components.
