CMF23V-393121-B

Common Mode Chokes Overview

The Triad Magnetics CMF23V-393121-B is a vertical mount common mode inductor from the CMF series. It features a nominal inductance of 39 mH with a tolerance of +30%/-50% at 1 kHz. The component supports a maximum DC current of 1.2 A and has a maximum DC resistance of 766 mohms. Designed for radial termination, it operates within a temperature range of -40°C to +105°C. The suffix '-B' denotes bulk packaging.

Common Mode Chokes Feature Summary

• Vertical mounting configuration for PCB integration
• Radial lead termination style
• Single-channel common mode filtering capability

Common Mode Chokes Applications

• Electromagnetic interference suppression in power supply circuits
• Common mode noise reduction in signal lines
• Filtering applications requiring high inductance values

Common Mode Chokes Procurement Notes

Verify the specific suffix against official documentation to confirm physical dimensions and orientation. The '-B' suffix indicates bulk packaging rather than tape-and-reel. Confirm that the vertical mounting style aligns with your board layout requirements before procurement.

Common Mode Chokes Selection Notes

Select this component when a vertical form factor is required for space-constrained designs. Ensure the 1.2 A current rating meets the circuit's operational demands. Verify that the 39 mH inductance value provides sufficient attenuation for the target frequency range compared to horizontal alternatives.

Common Mode Chokes Part Context

This part belongs to the Triad Magnetics CMF series of common mode chokes. It is distinct from the CMF23H variant primarily by its vertical mounting orientation, whereas the H-series uses horizontal mounting. Both share similar electrical characteristics but differ in physical footprint and installation method.

Common Mode Chokes Replacement Considerations

The CMF23H-393121-B is a direct electrical substitute but utilizes horizontal mounting. Verify mechanical clearance and PCB hole alignment if substituting between V (vertical) and H (horizontal) series variants.
