CMT-8120-B

Common Mode Chokes Overview

The CMT-8120-B is a two-line common mode choke manufactured by Triad Magnetics, designed for through-hole mounting. It features an inductance of 2.4 mH at 1 kHz and supports a maximum DC current rating of 17 A. The component has a maximum DC resistance (DCR) of 8 mOhm and withstands an AC voltage of 1500 V. Its vertical package measures 1.650 inches in height with four pins.

Common Mode Chokes Feature Summary

• Provides effective EMI suppression for power supply lines
• Supports high current applications up to 17 A
• Meets major international safety certifications including UL, CSA, IEC, and VDE

Common Mode Chokes Applications

• EMI suppression in switching power supplies
• Power line filtering for electronic equipment
• Industrial control systems requiring robust noise reduction

Common Mode Chokes Procurement Notes

Verify the specific suffix 'B' against the manufacturer's official datasheet to confirm pin configuration and mechanical dimensions. Ensure the selected variant matches the required through-hole footprint and lead spacing for your PCB layout. Cross-reference certification marks such as UL or VDE if regulatory compliance is mandatory for your final product assembly.

Common Mode Chokes Selection Notes

Select this component when high current handling capacity is required alongside significant common mode noise attenuation. The low DCR minimizes power loss during operation. Verify that the 1500 VAC insulation rating meets the isolation requirements of your circuit design. Consider the physical height constraints of your enclosure before finalizing the choice.

Common Mode Chokes Part Context

This part belongs to the CMT series of common mode chokes from Triad Magnetics. These components are engineered for general-purpose EMI filtering in AC power lines. The series offers various inductance and current ratings to suit different power levels while maintaining compact through-hole form factors suitable for standard manufacturing processes.

Common Mode Chokes Replacement Considerations

Check for direct substitutes within the same CMT series with compatible inductance and current ratings. Ensure any replacement maintains the same 1500 VAC insulation class and through-hole mounting style. Verify that alternative parts hold identical safety certifications if used in regulated markets.
