CM9900R-156

Common Mode Chokes Overview

The Delevan CM9900R-156 is a through-hole, PC mount common mode choke from the CM9900R series. It features a ferrite core and radial termination with a 5.1 mm lead spacing. The component provides an inductance of 15 mH at 100 kHz and has a maximum DC resistance of 2.24 Ohms. It operates within a temperature range of -55°C to +125°C. The 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 mounting for PCB integration
• Ferrite core construction for effective noise suppression
• Unshielded design suitable for standard electromagnetic interference filtering

Common Mode Chokes Applications

• Common mode noise filtering in electronic circuits
• Power supply line protection against electromagnetic interference
• Signal integrity enhancement in communication interfaces

Common Mode Chokes Procurement Notes

Verify the specific inductance test frequency, as datasheets may list 100 kHz or 1 kHz. Confirm the maximum DC current rating, which varies significantly across the CM9900R series based on inductance value. Ensure the package type matches the assembly requirements, as bulk and reel options exist. Check RoHS compliance status directly with the manufacturer for final regulatory confirmation.

Common Mode Chokes Selection Notes

Select this component when a 15 mH common mode choke is required for through-hole applications. Compare the 2.24 Ohm DC resistance against circuit loss tolerances. Verify that the 5.1 mm lead spacing fits the target PCB footprint. Consider the operating temperature range if the environment exceeds standard limits.

Common Mode Chokes Part Context

The CM9900R-156 belongs to the Delevan CM9900R series of common mode chokes. This series offers various inductance values ranging from microhenries to millihenries. All parts share similar physical dimensions and mounting styles, differing primarily in electrical characteristics such as inductance and current handling capabilities.

Common Mode Chokes Replacement Considerations

Check equivalent models from other manufacturers offering 15 mH common mode chokes with radial leads. Verify that substitute components match the 5.1 mm lead spacing and 21.3 x 18.8 mm footprint. Ensure the replacement meets the same thermal and electrical performance specifications.
