MIL-DTL-39012 Radio Frequency Connectors 
APPLICATION NOTES

1)  Plug coupling nuts and cable nut mounted connectors may have silicone rubber O-Ring seals which are an outgassing concern.  Connectors may require additional processing for outgassing control.  This should include a bake of the connector and removal or replacement of the silicone rubber O-Rings with fluorosilicone O-Rings which meet outgassing requirements.

2)  Temperature range for flexible and semirigid connectors is -65°C to +165°C.  Temperature range for PC mounted connectors is -65°C to +105°C.

3)  The use of safety wire is recommended to secure mated connectors together.

4)  B designated connectors which require special tooling for assembly are considered non-field replaceable and are not preferred.  Most are inactive for new design.

5)  Only series SMA connectors are recommended for satellite use in lower earth orbits.  Series N and TNC connectors are not recommended for use in lower earth orbits due to atomic oxygen corrosion concerns of their silver plating.
