Practical Values
The current-rating method gives
designers practical values appli-
cable 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 capacity of a
Connector/Contact
Acceptability
As previously stated, choosing the
appropriate connector/contact
combination is fundamental to the
successful function of all connec-
tors. The Selection Chart, shown at
right, is designed to simplify your
choice of connectors and their
acceptable contacts. Once you
have selected the wire size, cur-
rent-carrying capacity need,
number of positions required, and
the type of contacts needed in
your choice of connector, refer to
this matrix for a quick look at
exactly what is acceptable in a
given connector type.

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.
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.

and inches unless otherwise

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