CM9900-474

Common Mode Chokes Overview

The Delevan CM9900-474 is a through-hole PC mount common mode choke designed for noise suppression in electronic circuits. It features a ferrite core and radial termination style with a lead spacing of 5.1 mm. The component provides an inductance of 470 uH with a tolerance of +/- 25%. It supports a maximum DC current of 1.4 A and has a maximum DC resistance of 78 mOhms. The device operates within a temperature range of -55 C to +125 C and measures 18.8 mm in length, 21.3 mm in width, and 17 mm in height.

Common Mode Chokes Feature Summary

• Utilizes a ferrite core material for effective common mode noise filtering.
• Designed for PCB mounting with radial leads for secure mechanical attachment.
• Unshielded construction suitable for general-purpose electromagnetic interference reduction.

Common Mode Chokes Applications

• Data line filtering in communication equipment
• Noise suppression in power supply input stages
• Signal integrity protection in industrial control systems

Common Mode Chokes Procurement Notes

Verify the specific RoHS compliance status as documentation indicates non-compliance or varying data across sources. Confirm the packaging type, as bulk and reel options may exist within the series. Ensure the supplier provides official datasheets matching the 470 uH specification and 1.4 A current rating before finalizing procurement orders to avoid functional mismatches.

Common Mode Chokes Selection Notes

Select this component when a 470 uH common mode inductance is required for low-current applications up to 1.4 A. Consider the physical dimensions of 18.8 x 21.3 x 17 mm for PCB layout constraints. Evaluate the 78 mOhm DC resistance impact on circuit efficiency. Compare against the CM9900R-474 variant if RoHS compliance or reel packaging is mandatory for the production process.

Common Mode Chokes Part Context

The CM9900-474 belongs to the Delevan CM9900 series of common mode chokes. This series focuses on providing reliable noise filtration for through-hole PCB applications. The components are characterized by their robust ferrite cores and standardized radial pin configurations, making them suitable for integration into various analog and digital signal processing boards requiring EMI mitigation.

Common Mode Chokes Replacement Considerations

The CM9900R-474 is a documented substitute within the same series offering identical electrical specifications but potentially different packaging or compliance attributes.
