The component supports a maximum DC current of 350 mA and has a maximum DC resistance of 1.61 ohms. It 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 unspecified height.

Common Mode Chokes Feature Summary

• Radial leaded construction for through-hole PCB integration
• Common mode noise filtering capability for data lines
• Vertical PC mount design for space-constrained applications

Common Mode Chokes Applications

• Data line filtering in electronic circuits
• Common mode noise suppression in communication interfaces
• Power supply input filtering for sensitive electronics

Common Mode Chokes Procurement Notes

Verify the specific suffix (e.g., -106 vs -686) against the required inductance value, as the series includes variants with significantly different specifications such as 68 mH. Confirm that the 350 mA current rating meets the application's continuous DC requirements. Ensure the through-hole footprint matches the target PCB layout. Check RoHS compliance status if restricted substances are a concern for the final assembly.

Common Mode Chokes Selection Notes

Select this component when a 10 mH common mode choke is required for through-hole assembly. Compare the 1.61 ohm DC resistance against voltage drop constraints in the circuit. Evaluate the 350 mA saturation current against peak load conditions. Consider the physical size relative to available board space. Verify compatibility with automated insertion equipment if high-volume production is planned.

Common Mode Chokes Part Context

The CM9900 series consists of vertical mount common mode chokes manufactured by API Delevan. These components are engineered for reliability in filtering applications. The series offers various inductance values, including 10 mH and 68 mH options. They utilize radial leads for standard PCB mounting techniques. The design focuses on effective common mode noise attenuation.

Common Mode Chokes Replacement Considerations

Cross-reference with other 10 mH through-hole common mode chokes from manufacturers like Bourns or TDK. Ensure equivalent current ratings and DC resistance values are met. Verify mechanical footprint compatibility before substitution.
