CM9900-154

Common Mode Chokes Overview

The Delevan CM9900-154 is a common mode filter choke designed for PCB mounting with radial termination. It features an inductance of 150 µH at a test frequency of 1 kHz, with a tolerance of ±25%. The component supports a maximum DC current of 2.8 A and has a maximum DC resistance of 30 mΩ. Constructed with ferrite core material, it operates within a temperature range of -55°C to +125°C. Physical dimensions are 21.3 mm in length, 18.8 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 direct PCB integration
• Ferrite core design for effective common mode noise suppression
• High current handling capability up to 2.8 A

Common Mode Chokes Applications

• Data line filtering in electronic circuits
• EMI suppression in power supply inputs
• Signal integrity protection in communication interfaces

Common Mode Chokes Procurement Notes

Verify the specific suffix designation when ordering, as the CM9900R variant may differ in packaging or minor specifications compared to the standard CM9900 series. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as documentation indicates varying compliance levels across the product line. Ensure the required lead spacing matches the target PCB footprint before finalizing procurement decisions.

Common Mode Chokes Selection Notes

Select this component when a 150 µH common mode inductance is required for applications carrying up to 2.8 A. The unshielded design allows for flexible placement but requires consideration of magnetic field interaction with nearby components. Verify that the 30 mΩ DC resistance meets the voltage drop requirements of the circuit design under full load conditions.

Common Mode Chokes Part Context

This part belongs to the Delevan CM9900 series of common mode chokes. The series offers various inductance values tailored for different filtering needs. The CM9900-154 specifically targets applications requiring moderate inductance with high current capacity, distinguishing it from higher inductance variants like the CM9900R-106 which handle significantly lower currents.

Common Mode Chokes Replacement Considerations

The CM9900R-154 is a documented substitute within the same manufacturer's lineup, sharing identical electrical parameters including 150 µH inductance and 2.8 A current rating. Users should verify physical package compatibility and lead spacing consistency between the CM9900 and CM9900R prefixes before substitution.
