Q: How do I choose a quick connect female terminal?         

      1. Current carrying capacity: Selection is based on the maximum current expected in the circuit. In general, the larger the size, the higher the current that can be carried. Always make sure that the rated current of the selected female terminal is greater than or equal to the maximum current in the actual circuit to prevent overheating and malfunction.

         2. Voltage Rating: Know the operating voltage of the circuit and select a female terminal that can withstand that voltage. Insufficient voltage rating may result in insulation breakdown and electrical failure.

         3. Wire Diameter: Different sizes of female terminals are suitable for different wire diameters. To accurately measure the outer diameter of the wire, select the terminal hole diameter to match, in order to ensure a tight and reliable connection.

        4. Contact materials: High quality contact materials such as copper alloys have good electrical conductivity and corrosion resistance. This helps to reduce contact resistance and improve the stability and reliability of the connection.

       5. Plugging requirements: If frequent plugging and unplugging of the connection is required, the female terminal specifications with a high plugging and unplugging life should be selected to ensure stable performance in long-term use.

       6. Installation: Consider the installation method of the female terminals, whether it is surface mounted, through-hole mounted or other special mounting methods to adapt to your circuit board or equipment structure.

       7. Environmental factors: If the working environment is harsh, such as high temperature, high humidity, corrosive gases, etc., you need to choose the female terminal specifications with the appropriate protective performance and environmental resistance.

 When selecting quick-connect terminals, it is best to use the terminals recommended by the manufacturer. Take one of EAO's switches 84-8511.9620 as an example, as shown in the data sheet below:

As shown above, two of the dimensions are 2.8mm and 0.8mm - the first is the width of the insertion tab and the second is the thickness of the insertion tab.

If you can't find the exact size you need, you can use a smaller size, but the connection won't be as tight, so we need to check that it is suitable for the target application.

If you need to find a suitable quick connect by size or other parameters.please contact KeRunXinDa Electronics, we have a selection of model parameters screening service you.
