ATTRIBUTE DEFINITIONS
The following is a brief, simplified description of attributes.
TEMPERATURE RISE (Current Carrying Capacity, CCC):
1) EIA-364-70, Temperature Rise versus Current Test Procedure for Electrical Connectors and Sockets.
2
2) When current passes through a contact, the temperature of the contact increases as a result of I R (resistive)
heating.
3) The number of contacts being investigated plays a significant part in power dissipation and therefore
temperature rise.
4) The size of the temperature probe can affect the measured temperature.
5) Copper traces on PC boards will contribute to temperature rise:
a. Self heating (resistive)
b. Reduction in heat sink capacity affecting the heated contacts
6) A de-rating curve, usually 20%, is calculated.
7) Calculated de-rated currents at three temperature points are reported:
a. Ambient
о
b. 80 C
о
c. 95 C
о
d. 115 C
8) Typically, neighboring contacts (in close proximity to maximize heat build up) are energized.
9) The thermocouple (or temperature measuring probe) will be positioned at a location to sense the maximum
temperature in the vicinity of the heat generation area.
10) A computer program, TR 803.exe, ensures accurate stability for data acquisition.
11) Hook-up wire cross section is larger than the cross section of any connector leads/PC board traces, jumpers,
etc.
12) Hook-up wire length is longer than the minimum specified in the referencing standard.

DATA SUMMARIES
TEMPERATURE RISE - (Current Carrying Capacity, CCC):
1) High quality thermocouples whose temperature slopes track one another were used for temperature
monitoring.
2) The thermocouples were placed at a location to sense the maximum temperature generated during testing.
3) Temperature readings recorded are those for which three successive readings, 15 minutes apart, differ less
than 1° C (computer controlled data acquisition).
4) Adjacent contacts were powered:
a. Linear configuration with 1 adjacent conductors/contacts powered
