Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before integration, as distributor listings may contain conflicting specifications. Confirm package availability and reel quantities directly with the manufacturer or authorized distributors to ensure supply chain alignment. Cross-reference the part number alias CUW0805-121M-N if sourcing from legacy inventories.
Selection Notes
Select this component when a 90 Ohm impedance at 100 MHz is required for differential pair filtering. Ensure the PCB layout accommodates the 2.29 x 1.52 mm footprint. Verify that the 1A current rating meets the operational requirements of the target circuit. Consider the unshielded nature of the device for placement relative to sensitive analog components.
Part Context
This component belongs to the BWCU series of compact common mode chokes from Pulse Electronics. The series is engineered for portable electronics and high-density applications requiring minimal board space. It serves as a specialized filter for maintaining signal integrity in high-speed serial communication protocols.
Replacement Considerations
The part number alias CUW0805-121M-N refers to the same component. Verify pinout compatibility and physical dimensions when substituting with other 0805-sized common mode chokes from different manufacturers.
