Procurement Notes

Verify that the specific order matches the M3933/14-08N designation, as suffixes like 'S' or 'N' may indicate different construction materials or qualification levels. Confirm compliance with MIL-DTL-M3933 requirements if military certification is mandatory for the application. Check for RoHS non-compliance status prior to procurement to ensure alignment with environmental regulations. Ensure SMA connector gender and mating compatibility are verified against system interfaces.

Selection Notes

Select this component when a fixed 4dB attenuation is required at frequencies up to 12.4 GHz. Consider the 2W power rating to ensure it exceeds the maximum expected signal power in the circuit. Verify that the SMA interface matches the existing system architecture. Evaluate the need for MIL-DTL-M3933 compliance versus commercial alternatives based on operational environment demands.
