First, a base curve showing cur-  
rent levels versus T-rise for a  
single circuit and the largest wire  
size (See figure 1). This repre-  
sents the maximum current  
capacity of the contact. The  
curve is usually flat up to 75°C  
ambient and then drops off. Up  
to 75°C, the 30°C T-rise limits  
the amount of current, and  
above 75°C the current must be  
reduced to keep the combina-  
tion of ambient temperature  
and T-rise from exceeding the  
maximum operating tempera-  
ture of 105°C.

To demonstrate the method of  
specifying current, consider the  
following application conditions;  
an ambient temperature of 65°C, a  
50% loading of contacts in the

housing, and 20 AWG [0.6mm ]  
wire.

[0.6mm ] wire is 0.68.  
Next are rating factors; a table  
of multipliers to account for  
connector loading and for  
smaller wire sizes (See figure 2).  
The designer first determines  
the base current for the ambi-  
ent conditions of the  
application; then multiplies this  
base current by the rating fac-  
tors to find the current level for  
the application’s loading factor  
and wire size.  
The specific rating for this appli-  
cation is the product of the  
base rating and the rating factor:  
14 x 0.68 = 9.5 ampere

However, if the ambient tem-  
perature is 80°C the allowable  
T-rise becomes 25°C. The base  
current must be lowered to 12.8  
ampere so that the 105°C maxi-  
mum operating temperature is  
not exceeded. The current rat-  
ing then becomes:

combination is fundamental to the  
successful function of all connec-
