CM9900R-825

Common Mode Chokes Overview

The Delevan CM9900R-825 is a through-hole common mode filter choke designed for PCB mounting. It features a ferrite core and radial termination with a 5.1 mm lead spacing. The component provides an inductance of 8.2 mH (8200 uH) with a tolerance of ±25%. It supports a maximum DC current of 350 mA and has a maximum DC resistance of 1.4 ohms. The unit operates within a temperature range of -55°C to +125°C and measures 21.3 mm x 18.8 mm x 17 mm.

Common Mode Chokes Feature Summary

• Radial through-hole construction for direct PCB integration
• Ferrite core design for effective common mode noise suppression
• Unshielded configuration suitable for standard electromagnetic environments

Common Mode Chokes Applications

• Power supply input filtering
• Signal line noise reduction
• Electromagnetic interference suppression in electronic circuits

Common Mode Chokes Procurement Notes

Verify the specific manufacturer designation, as sources list both Delevan and API Delevan Inc. Confirm the exact datasheet version matches the required electrical tolerances and physical dimensions. Ensure the ordering suffix corresponds to the correct packaging format, such as reel or bulk, as indicated in official documentation.

Common Mode Chokes Selection Notes

Select this component when an 8.2 mH inductance value is required for common mode applications. Ensure the circuit current does not exceed 350 mA to prevent saturation. Verify that the 5.1 mm lead spacing fits the target PCB layout and that the unshielded nature meets the system's EMI requirements.

Common Mode Chokes Part Context

This part belongs to the CM9900R series of common mode chokes from Delevan. The series offers various inductance values ranging from low microhenries to high millihenries, all sharing similar physical footprints and mounting styles for consistent board design across different filtering needs.

Common Mode Chokes Replacement Considerations

Check for parts with identical 8.2 mH inductance, 350 mA rating, and 5.1 mm pitch. Cross-reference with other Delevan CM9900 variants if available.
