CM9900-225

Common Mode Chokes Overview

The Delevan CM9900-225 is a single-channel common mode filter choke designed for PCB mounting. It features radial termination and an unshielded ferrite core construction. The component provides an inductance of 2.2 mH with a tolerance of ±25%. It supports a maximum DC current of 550 mA and exhibits a maximum DC resistance of 431 milliohms. The device 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.

Common Mode Chokes Feature Summary

• Radial through-hole termination for direct PCB integration
• Unshielded ferrite core design for common mode noise suppression
• Wide operational temperature capability from -55°C to +125°C

Common Mode Chokes Applications

• Data line filtering in electronic circuits
• Common mode noise suppression in signal paths
• PCB-mounted electromagnetic interference mitigation

Common Mode Chokes Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets may be managed by other entities. Confirm RoHS compliance status, as documentation indicates non-compliance for this specific part number variant. Ensure the ordering suffix matches the required packaging format, typically bulk for this series. Validate that the 2.2 mH inductance rating meets the circuit requirements before procurement.

Common Mode Chokes Selection Notes

Select this component when a 2.2 mH common mode choke is required for low-current applications up to 550 mA. The unshielded design suits environments where magnetic coupling with adjacent components is not critical. Verify that the 431 milliohm DC resistance aligns with power loss constraints. Consider the physical footprint of 18.8 mm by 21.3 mm for board layout compatibility.

Common Mode Chokes Part Context

The CM9900-225 belongs to the Delevan CM9900 series of PC mount common mode chokes. This series utilizes ferrite cores and radial leads for standard through-hole assembly. The product falls under the broader category of inductors, chokes, and coils, specifically serving as a data line filter for noise reduction in electronic systems.

Common Mode Chokes Replacement Considerations

Cross-reference with other CM9900 series variants such as CM9900R-475 or CM9900-566 if different inductance values are acceptable. Verify pin spacing and physical dimensions against alternative suppliers to ensure mechanical fit. Check equivalent electrical parameters including saturation current and impedance characteristics.
