CM9900-275

Common Mode Chokes Overview

The Delevan CM9900-275 is a through-hole, PC mount common mode choke belonging to the CM9900 series. It utilizes a ferrite core and features radial termination with a 5.1 mm lead spacing. The component provides an inductance of 2700 uH with a tolerance of +/- 25%. It supports a maximum DC current of 550 mA and has a maximum DC resistance of 469 mOhms. Operating temperatures range from -55 C to +125 C. Physical dimensions are 18.8 mm length, 21.3 mm width, and 17 mm height. Testing is conducted at 1 kHz.

Common Mode Chokes Feature Summary

• Radial through-hole mounting for PCB integration
• Ferrite core construction for EMI suppression
• Unshielded design configuration

Common Mode Chokes Applications

• Data line filtering
• Common mode noise suppression
• EMI/EMC mitigation circuits

Common Mode Chokes Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm minimum order quantities and packaging formats, which may vary between bulk and reel options. Ensure the specific part number matches the required inductance and current ratings for the target application circuit design.

Common Mode Chokes Selection Notes

Select this component when a 2700 uH common mode choke is required for through-hole assembly. Consider the 550 mA current rating and 469 mOhms resistance for power loss calculations. Verify that the unshielded nature meets the electromagnetic interference requirements of the final equipment enclosure.

Common Mode Chokes Part Context

This component is part of the Delevan CM9900 series of common mode chokes. These components are designed for general-purpose EMI filtering applications. The series offers various inductance values while maintaining consistent physical footprints and mounting styles for standardized PCB layouts.

Common Mode Chokes Replacement Considerations

Check for CM9900R-275 if RoHS compliance is mandatory, as the standard CM9900 series may not meet current environmental regulations. Verify pin compatibility and inductance tolerances before substituting.
