CM9900-226

Common Mode Chokes Overview

The Delevan CM9900-226 is a through-hole, PC mount common mode choke belonging to the CM9900 series. It features a ferrite core with an inductance of 22 mH and a tolerance of ±25%. The component supports a maximum DC current of 220 mA and has a maximum DC resistance of 3.49 ohms. It operates within a temperature range of -55°C to +125°C. Physical dimensions are 18.8 mm in length, 21.3 mm in width, and 17 mm in height, with a lead spacing of 5.1 mm.

Common Mode Chokes Feature Summary

• Radial through-hole construction for PCB mounting
• Ferrite core design for high-frequency noise suppression
• Unshielded configuration

Common Mode Chokes Applications

• Common mode noise filtering in electronic circuits
• Power supply line interference suppression
• Signal integrity protection in sensitive equipment

Common Mode Chokes Procurement Notes

Verify the specific suffix (e.g., R vs. standard) as it may indicate packaging or variant differences. Confirm RoHS compliance status directly from the manufacturer datasheet, as sources vary. Ensure the required inductance value matches the application needs before ordering. Check availability as some listings indicate non-stocked status.

Common Mode Chokes Selection Notes

Select this component when a 22 mH common mode choke is required for through-hole assembly. Consider the 220 mA current rating and 3.49 ohm DC resistance limits during circuit design. The unshielded nature requires consideration for electromagnetic interference placement relative to other components on the board.

Common Mode Chokes Part Context

This part is manufactured by API Delevan Inc. under the CM9900 series of common mode chokes. The series offers various inductance values for different filtering requirements. The CM9900-226 specifically targets applications needing higher inductance for low-frequency noise attenuation compared to lower-value variants in the same family.

Common Mode Chokes Replacement Considerations

Cross-reference with other Delevan CM9900 series parts for different inductance values. Verify mechanical footprint compatibility if substituting with similar radial chokes from other manufacturers.
