When selecting pin and female connectors, consideration should be given to the electrical specifications of the product. What are the current and current regulations for the product, and whether the connector can be effectively used in such electrical conditions? This situation regarding electrical regulations requires us to consider. In addition, other electrical standards must also be considered: resistors, allowable resistor variation, millivolt drop, high current, high operating voltage value, surge current, characteristic impedance, VSWR (standing wave ratio), plug-in loss, and EMI shielding high efficiency.  

The temperature, environmental humidity, and other environmental standards are determined by the location of the connector, so the location and estimated environment should be taken into account. And what are the shelf lives and information about other storage standards. The discussion of the environment should also include provisions on impact and mechanical vibration, including regulations derived from international maritime transport, as well as production and manufacturing environmental standards such as welding temperature and welding cycle time delay time. The connector distributor stated that the area around the convergence type continuous current guided by the pin and female connectors is the region where the maximum temperature occurs.  

For connectors, which sizes and footprints are reasonable; What is the allowable standard tolerance; What is the cost of inserting and unloading terminals; What is the durability of the connector (frequency of mutual mating when plugged in and out)? This reason must be considered when selecting electrical connectors.
