What do I need to be aware of when choosing terminal connectors?

I. Selection of terminal connectors need to pay attention to what issues?1, current requirements current requirements can be said to be an important aspect of the terminals to be considered, because more than the rated current through the rated requirements will lead to heating of the terminals, overheating temperature may damage the terminals. So in the selection of terminals, need to ensure that the selected terminals have a high current handling requirements, if the application requirements for the expected rated current of 2A, should choose the rated current of 3A terminals will be sufficient. 2, voltage requirements voltage requirements are also terminals need to be taken into account within the problem, because the voltage will cause dielectric breakdown problems, so that the terminal voltage is too high may lead to the neighboring terminals between the current leakage. The current leakage between neighboring terminals. Although high voltage requirements in the design is usually rare, which is why the voltage is less than 100V is usually ignored voltage considerations, but in the selection of terminals before checking the voltage parameters is very important. 3, environmental performance requirements for the connector selection of terminals, the environmental factors are important to consider, because of high temperatures and vibration and other environmental factors will have an impact on the performance of terminals, so make sure that the terminals have a dielectric breakdown problems, so that terminals with too high voltage may lead to leakage of current between neighboring terminals. Therefore, the need to ensure that the terminals have high mechanical strength and good environmental performance.
