Common Mode Chokes Procurement Notes

Verify the specific suffix '823' against the manufacturer's official documentation to confirm the exact inductance value and current rating, as series designations may vary. Ensure the procurement channel sources genuine API Delevan components to guarantee compliance with RoHS standards and specified electrical parameters. Cross-reference the part number with the latest catalog to avoid substitutions with similar models like CM9900R-474 or CM9900-823 which may have different specifications.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring robust common mode noise suppression for data lines operating within the specified temperature range. The 2.8 A current rating suits applications with moderate power requirements, while the 82 µH inductance targets specific frequency attenuation needs. Consider the unshielded nature of the device for placement relative to sensitive components to prevent magnetic coupling issues.

Common Mode Chokes Part Context

This part belongs to the CM9900R series of PC mount common mode chokes from API Delevan. The series includes variants with different inductance values, such as CM9900R-474 (470 µH) and CM9900R-105 (1000 µH). These components are designed for through-hole assembly and are commonly used in telecommunications and data transmission equipment to filter electromagnetic interference.

Common Mode Chokes Replacement Considerations

Direct substitutes include other CM9900R series parts if inductance differences are acceptable, such as CM9900R-474. Verify that any replacement maintains the same package dimensions, lead spacing, and current handling capabilities to ensure mechanical and electrical compatibility in the existing design.
