About the M39012/26-0503 TNC Plug, RF Mil-Spec
The M39012 26-0503 TNC Plug RF Mil-Spec connector is a qualified military RF coaxial plug procured to slash sheet MIL-PRF-39012/26, which covers cabled TNC-series plugs with pin contacts (Class 2). TNC connectors are 50-ohm RF connectors with a threaded coupling nut; the /26 slash sheet specifies a frequency range of 0–11 GHz, an operating temperature range of −65 °C to +165 °C and a minimum voltage rating of 375 V rms. The threaded coupling maintains a stable, low-noise interface under vibration, which is the principal reason TNC is preferred over bayonet-coupled BNC in airborne and vehicle-mounted systems. The -0503 dash number identifies the specific connector configuration and cable group within the slash sheet, so please confirm your cable type and any QPL traceability requirements in the RFQ to ensure the correct variant and documentation are quoted.
