CMT2-1-R

Common Mode Chokes Overview

The Eaton CMT2-1-R is a through-hole common mode choke belonging to the CMT series. It provides an inductance of 30 mH at 10 kHz with a maximum current rating of 1.5 A. The component features a typical DC resistance (DCR) of 350 mOhm and utilizes a vertical package with four pins. Designed for power line filtering, it operates within a temperature range of -40°C to 125°C.

Common Mode Chokes Feature Summary

• Provides high common mode noise suppression via 30 mH inductance
• Supports continuous currents up to 1.5 A
• Utilizes vertical through-hole mounting for PCB integration

Common Mode Chokes Applications

• Power line filtering
• EMI suppression in electronic circuits
• Common mode noise reduction

Common Mode Chokes Procurement Notes

Verify the specific datasheet version before procurement, as Eaton Electronics may issue Product Change Notifications (PCNs) affecting dimensions or materials. Confirm that the vertical pin configuration matches the target PCB footprint. Ensure the 1.5 A current rating meets the application's thermal requirements under worst-case operating conditions.

Common Mode Chokes Selection Notes

Select this component when high inductance is required for low-frequency noise attenuation in two-line power applications. The 350 mOhm DCR offers a balance between conduction loss and magnetic performance. Verify that the 125°C maximum operating temperature aligns with the system's ambient environment and self-heating characteristics.

Common Mode Chokes Part Context

This part belongs to the Eaton CMT series of common mode chokes, designed for robust EMI filtering. The series typically employs ferrite cores to achieve high impedance against common mode signals while maintaining low differential mode interference. These components are standard solutions for power supply input stages.

Common Mode Chokes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Any replacement must match the 30 mH inductance, 1.5 A current rating, and vertical through-hole form factor.
