Practical Values
The current-rating method
gives designers practical val-
ues applicable to their appli-
cations. While the specified
current levels for a contact
may be lower than for other
testing methods, they are
more realistic and simplify
the system design process.
"Spec-manship" is replaced
by a realistic assessment of
the current-carrying capacity
of a contact under varying
conditions of temperature,
connector loading, and wire
size.
contact. The curve is usu-
ally 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 combination of ambi-
ent temperature and T-rise
from exceeding the maxi-
mum operating tempera-
ture of 105°C.
Next are rating factors, a
table of multipliers to
account for connector
loading and for smaller
wire sizes. The designer
first determines the base
current for the ambient
conditions of the applica-
tion, then multiplies this
base current by the rating
factors to find the current
level for the application's
loading factor and wire
size.
Dimensions are shown for

Graph shows the relationship between base current, ambient tem-
perature, and contact T-rise.
Rating factors allow the base current to be adjusted for various con-
nector loading and wire sizes.
An Example:
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
[0.6 mm2] wire.

From Figure 1, the base current rating is 14 ampere with 18
AWG [0.8 mm2] wire.
Figure 2, the rating factor for 50% loading and 20 AWG [0.6
mm2] wire is 0.68.
The specific rating for this application is the product of the
base rating and the rating factor:
Each of the contacts can carry 9.5 ampere.
However, if the ambient temperature is 80
T-rise becomes 25°C. The base current must be lowered to
12.8 ampere so that the 105
ture is not exceeded. The current rating then becomes:
