Procurement Notes
Verify current availability status as the product is listed as obsolete by the manufacturer. Confirm compatibility with existing chassis mounting hardware due to specific dimensional requirements. Check for alternative sourcing channels if original stock is unavailable. Ensure storage conditions meet specifications for electronic components. Validate that the 50 Ohm impedance matches system requirements before integration.
Selection Notes
Select this component when high power handling and broadband RF performance are required. Consider the physical size constraints due to the 27.94 mm length. Evaluate thermal management needs given the 400 W rating. Verify that the flange mount interface suits the mechanical design. Assess if the 5% tolerance meets circuit precision requirements.
Part Context
This part belongs to the CHF11050CBF series of RF power resistors from Bourns. The series is characterized by high power ratings and robust construction for RF environments. The CHF11050CBF500L specifically provides a standard 50 Ohm termination value. The series supports various resistance values within the same form factor.
Replacement Considerations
Public confirmed substitute part numbers are not available. The model is marked as obsolete. Engineers should consult Bourns documentation for discontinued product alternatives or redesign using currently active series components.
