Contact Current Carrying Capability
The total current capacity of each contact in a connector is dependent upon the heat rise resulting from the combina-
tion of electrical loads on all the contacts in the connector arrangement and the maximum ambient temperature in
which the connector will be operating. Caution must be taken to assure that these combinations of conditions do not
cause the internal temperature of the connector to exceed the maximum operating temperature of the housing mate-
rial. There are several variables which must be considered when determining this maximum current carrying capability
for your application.
These variables are:
a. Wire Size-Larger wire will carry more current since it has less resistance to current flow; therefore, it generates less
heat. The wire also conducts heat away from the connector.
b. Connector Size-In general, the more circuits in a connector, the less current per contact can be carried.
c. Ambient Temperature - The higher the ambient temperature, the less current can be carried.
