Practical Va l u e s
The current-rating method
gives designers practical
values applicable to their
applications. 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 capac-
ity of a contact under vary-
ing conditions of
temperature, connector
loading, and wire size.
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 com-
bination of ambient tem-
perature and T-rise from
exceeding the maximum
operating temperature 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 tempera-
ture, and contact T-rise.
Rating factors allow the base current to be adjusted for various connec-
tor 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 mm
( C o n t i n u e d )
From Figure 1, the base current rating is 14 ampere with
18 AWG [0.8 mm
Figure 2, the rating factor for 50% loading and 20 AWG
[0.6 mm
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.
H o w e v e r, if the ambient temperature 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 maximum operating temper-
a t u re is not exceeded. The current rating then becomes:
14 x 0.68 = 9.5 ampere
12.8 x 0.68 = 8.7 ampere.
