Temperature/Current Rating
Derating curves define the max. current that
can be applied to a connector at a given ambi-
ent temperature so that the additional tem-
perature rise caused by the current does not
exceed the material limit of the connector.
The following curves show the max. currents
based on the assumption attached: As factors
like current load per contact, wire size etc.
may be different in your application. This
chart is an indication only.

General recommendations for the selec-
tion of Trident contacts are listed below.
Platings: Tin is recommended for most
applications (with 50 or fewer mating
cycles). It is cost effective and matches
well to most wires. Gold is preferred for
special situations. Gold resists oxidation,
has high surface conductivity, and has a
low coefficient of friction. These features
make gold the preferred plating for low
level signals (a rule of thumb is <100
mA), corrosive environments (for
unsealed connectors), and for increased
mating cycles. The electrical performance
of the contact is determined at the sur-
face of the contact. For this reason, flash
gold platings are suitable for applications
with 50 or fewer mating cycles. Thicker
gold platings are recommended
for more than 50 mating cycles.
All Trident Contacts are RoHS
Compliant.
Stamped versus Machined: The two
part stamped contacts are manufactured
to precise tolerances and are field proven.
Derived in accordance with IEC 512-3,
Test 5b.
Figures are for maximum wire sizes.
Smaller wires will reduce rating.
All contacts equally loaded.
PCB mounted connectors will be limited
by PCB performance.
Bunched cables will further reduce values.
Cable insulation type will affect
temperature and loading.
Figures are for maximum connector
sizes in each range. Smaller connectors
will increase rating.
They can be supplied on reels which
lowers assembly costs for volume
production. Machined contacts offer
improved precision and durability. They
are recommended for applications with
more than 200 mating cycles.
Crimp versus Solder: Crimp contacts
offer improved electrical performance,
strain relief and quality control compared
to solder cup contacts. Solder cup

contacts are recommended for low
volume and prototype applications
where the added cost of crimp tools is
not justified.
High Conductivity: These contacts
use a different base material then the
standard contacts. They are recommend-
ed for high current applications. These
contacts will also reduce the derating of
connectors with several high current lines.
