Connector Construction and Materials

The material used in the connector can affect the output power handling capability, in which the electrical polarization material has a greater impact. Most connectors today employ one of several classes of fluoropolymers to obtain and support the center conductor of the point connector, of which polytetrafluoroethylene (PTFE) is the most widely used. Gas-electric polarized connectors (such as high-precision 2.4, 2.9 or 3.5mm connectors) can avoid the application of PTFE and use higher temperature materials (such as Ultem1000). Under other conditions, high-power connectors can use heat transfer electrolytic media to ensure better center conductor cooling than PTFE.

Another material of interest is the coating in the center conductor. Sustained high temperatures can also cause rapid air oxidation of touched materials, increasing resistor and I2R losses. This type of increased output power loss increases the temperature, which eventually leads to an uncontrollable situation. Unfortunately, this approach is not as easy to perform as the heating of the electrolytic medium, because it is very dependent on natural conditions (such as laboratory and deep sea) and its generally unique electroplating process materials and thickness. However, the more easily manifested electrical polarization material limitation is the more typical short-term failure mode and output power limitation.
