The body is gold-plated stainless steel, the centre contact is gold-plated beryllium copper, and the dielectric is PTFE. Threaded fastening gives a vibration-resistant mate with the matching SMA plug.
The 50 Ohm impedance and 12.4 GHz max frequency define the signal path — this is a genuine RF-grade SMA, not a low-frequency power or control connector. The 335 V rating is above typical RF signal levels, so it can handle DC bias injection or low-power RF transmission without voltage breakdown concerns. The -65°C to 125°C operating range covers military, aerospace, and outdoor telecom thermal profiles.
The 1053392-1 is listed as Obsolete by TE Connectivity. No official successor order code is on record. For a BOM that specifies this exact order code, the procurement path is the surplus and broker channel; a same-day quote can be requested with the target quantity.
