The gold-plated stainless steel body and gold-over-beryllium copper center contact are standard for high-reliability RF interconnects where corrosion resistance and consistent impedance matter. What sets this particular SMA apart is the extended insulation and hermetic seal — features that push it beyond a standard panel jack into applications where moisture ingress or high-voltage creepage are a concern.
No direct replacement from TE has been published, so a cross-reference search should verify the fit dimensions and the hermetic seal requirement before substituting.
RF Construction and Duty
The dielectric is PTFE, which keeps the insertion loss stable across temperature and frequency.
