Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as documentation indicates non-compliance. Check for obsolescence notices and validate replacement part numbers such as the CM5022R800R-10 if availability is required. Ensure storage conditions meet specified environmental standards.
Selection Notes
Select this component when designing circuits requiring eight-channel common mode filtering with high current capacity. The 80 Ohm impedance at 100 MHz targets specific EMI frequencies. Verify that the 5A rating meets the system's peak load requirements. Consider the vertical leaded package for PCB layout constraints and thermal management needs.
Part Context
This component belongs to the Laird CM series of signal integrity products. It is manufactured by Laird-Signal Integrity Products, a division focused on electromagnetic interference solutions. The series includes various configurations for different line counts and current ratings, serving diverse electronic protection needs.
Replacement Considerations
The CM5022R800R-10 is listed as a direct substitute. Verify pin compatibility and impedance characteristics before implementation.
