CMF23H-393121-B

Common Mode Chokes Overview

The Triad Magnetics CMF23H-393121-B is a common mode inductor from the CMF series, designed for through-hole horizontal mounting. It features a nominal inductance of 39 mH with a tolerance of +50%/-30% at 1 kHz and a maximum DC current rating of 1.2 A. The component has a maximum DC resistance of 766 mOhms and withstands 1.5 kVAC. It operates within a temperature range of -40°C to +105°C.

Common Mode Chokes Feature Summary

• Horizontal radial leaded construction for PCB integration
• High voltage isolation capability of 1.5 kVAC
• Robust thermal performance up to 105°C

Common Mode Chokes Applications

• Power supply input filtering
• EMI suppression in AC line circuits
• Frame choke applications

Common Mode Chokes Procurement Notes

Verify the suffix '-B' indicates bulk packaging configuration. Confirm horizontal mounting orientation requirements against vertical alternatives like the CMF23V series. Ensure the 1.2A current rating meets circuit demands. Check RoHS compliance status via official datasheet.

Common Mode Chokes Selection Notes

Select this part for horizontal space-constrained designs requiring 39mH common mode rejection. Compare DCR and current ratings against similar CMF series variants. Verify physical dimensions (26.5mm length) fit the assembly layout. Consider the CMF23V series if vertical mounting is preferred.

Common Mode Chokes Part Context

This component belongs to the Triad Magnetics CMF series of common mode chokes. These are typically used for noise suppression in power lines. The CMF23H variant specifically denotes horizontal pin configuration, distinguishing it from vertical or other form factors within the same electrical specification family.

Common Mode Chokes Replacement Considerations

The CMF23V-393121-B offers identical electrical specifications but utilizes a vertical mounting style. Verify mechanical clearance and board layout compatibility before substituting. No other direct substitutes are confirmed in public documentation.
