CM9900-104

Common Mode Chokes Overview

The Delevan CM9900-104 is a through-hole common mode choke designed for PCB mounting. It features a ferrite core and radial termination with a 5.1 mm lead pitch. The component provides an inductance of 100 µH at a test frequency of 1 kHz, with a tolerance of ±25%. It supports a maximum DC current of 2.8 A and has a maximum DC resistance of 25 mΩ. The unit operates within a temperature range of -55 °C to +125 °C. Physical dimensions are 18.8 mm x 21.3 mm x 17 mm.

Common Mode Chokes Feature Summary

• Radial through-hole construction for standard PCB integration
• Ferrite core material for effective noise suppression
• High current handling capability up to 2.8 A

Common Mode Chokes Applications

• Data line filtering in electronic circuits
• Common mode noise reduction in power supplies
• Signal integrity protection in communication interfaces

Common Mode Chokes Procurement Notes

Verify the specific part number suffix when ordering, as variations such as CM9900R-104 may exist within the same series. Confirm that the required inductance value matches the design specifications exactly. Ensure the physical footprint aligns with the 5.1 mm lead pitch and overall package dimensions. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate availability through authorized distributors given potential stock fluctuations.

Common Mode Chokes Selection Notes

Select this component when a 100 µH inductance is required for common mode noise attenuation. The 2.8 A current rating suits applications with moderate DC bias currents. The unshielded design requires consideration of magnetic field interaction with nearby components. The wide operating temperature range allows use in harsh environments. Verify that the 25 mΩ DC resistance meets the voltage drop constraints of the circuit design.

Common Mode Chokes Part Context

This component belongs to the Delevan CM9900 series of common mode chokes. The series offers various inductance values tailored for different filtering requirements. These devices are manufactured by API Delevan, a specialist in passive components. The CM9900 series is characterized by its robust through-hole construction and ferrite core technology. It serves as a fundamental element for electromagnetic interference suppression in industrial and commercial electronics.

Common Mode Chokes Replacement Considerations

The CM9900R-104 is a variant within the same series offering identical electrical characteristics. Cross-referencing with other manufacturers requires matching the 100 µH inductance, 2.8 A current rating, and 25 mΩ resistance. Physical compatibility depends on verifying the 5.1 mm lead pitch and housing dimensions.
