SMA Jack for 18 GHz Signal Paths
The 901-5PF705590AE: The threaded coupling and flange mount lock the interface tight against vibration drift — the coupling nut torque should hit 0.79–1.13 N·m per the SMA standard to keep the impedance transition clean. The stainless steel body handles corrosion better than the brass-bodied 901-9891-RFX, and the extended insulation on the center contact adds creepage distance for applications where altitude or voltage transients risk flashover.
The 500-cycle rating on this SMA jack exceeds the typical range for a standard SMA. In a test-equipment rack where the connector sees daily cable swaps, that 500-cycle life translates to years of service before the contact resistance drifts.
