CMF23H-273141-B

Common Mode Chokes Overview

The Triad Magnetics CMF23H-273141-B is a common mode frame choke designed for horizontal mounting with radial leads. It features an inductance of 27 mH at a test frequency of 10 kHz, with a tolerance of +50%/-30%. The component supports a maximum DC current of 1.4 A and has a maximum DC resistance of 484 mOhms. It operates within a temperature range of -40°C to +105°C and provides creepage and clearance greater than 3mm. The physical dimensions are 26.5 mm in length, 24.8 mm in width, and 14 mm in height.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression with high insulation clearance exceeding 3mm
• Designed for horizontal PCB mounting using radial through-hole termination
• Constructed as a frame choke suitable for robust electromagnetic interference filtering

Common Mode Chokes Applications

• LED lighting power supply circuits
• General electronic equipment EMI filtering
• Power line noise suppression in consumer electronics

Common Mode Chokes Procurement Notes

Verify the specific suffix designation during procurement, as it indicates bulk packaging configuration rather than electrical performance changes. Confirm that the required inductance tolerance and current ratings align with the circuit design specifications before integration. Ensure the horizontal mounting style fits the mechanical constraints of the target enclosure.

Common Mode Chokes Selection Notes

Select this component when a 27 mH common mode inductor is required for horizontal installation. The 1.4 A current rating and 484 mOhm DCR define the thermal and efficiency limits. Verify that the operating environment stays within the specified -40°C to +105°C range and that the >3mm clearance meets safety isolation requirements for the application voltage.

Common Mode Chokes Part Context

This part belongs to the Triad Magnetics CMF series of common mode chokes. The series offers various inductance values and current ratings tailored for different power levels. The CMF23H variant specifically denotes the horizontal mounting footprint, distinguishing it from vertical mount options within the same product family.

Common Mode Chokes Replacement Considerations

Direct substitutes must match the 27 mH inductance, 1.4 A current rating, and horizontal radial package. Verify compatibility with the 484 mOhm DCR and 105°C temperature rating. Cross-reference with other manufacturers' common mode chokes ensuring identical pinout and mechanical dimensions for drop-in replacement.
