CME375-9

Common Mode Chokes Overview

The Triad Magnetics CME375-9 is a switchmode common mode filter choke designed for power line applications. It features an inductance of 176.1 mH with a maximum DC current rating of 870 mA. The component has a maximum DC resistance of 1.98 ohms and operates within a temperature range of -40°C to +80°C. It utilizes a vertical through-hole mounting style with four pins and measures 38.10 mm in length, 32.00 mm in width, and up to 29.97 mm in height.

Common Mode Chokes Feature Summary

• Provides common mode noise filtering for power lines
• Designed for switchmode and high frequency applications
• Vertical through-hole construction for PCB integration

Common Mode Chokes Applications

• Power line filtering
• Switchmode power supply input stages
• High frequency circuit noise suppression

Common Mode Chokes Procurement Notes

Verify the specific inductance value against official datasheets, as conflicting data exists between 176.1 mH and 1.8 mH in available sources. Confirm the operating temperature range and physical dimensions match design requirements. Ensure the vertical pin configuration is compatible with the target PCB layout before procurement.

Common Mode Chokes Selection Notes

Select this component when high inductance is required for common mode noise reduction in power lines. The 870 mA current rating suits moderate power applications. Verify the 1.98 ohm DC resistance fits system loss constraints. The vertical package requires adequate board clearance for the 29.97 mm height.

Common Mode Chokes Part Context

Part of the CME series from Triad Magnetics, which includes various common mode chokes with different inductance and current ratings. This series is characterized by vertical mounting options and suitability for switchmode applications. Other variants include CME375-2, CME375-6, and CME375-8.

Common Mode Chokes Replacement Considerations

Check CME375-6 (43.6 mH, 1.75 A) or CME375-8 (111.6 mH, 1.1 A) if lower inductance or higher current is acceptable. Verify that alternative components maintain the same vertical pin configuration and physical footprint constraints.
