CURRENT CARRYING CAPACITY
1. Purpose
1.1. To determine the amount of current the device under test (DUT) can safely carry
over the operating temperature range of the DUT.
1.2. Contact loading will also be addressed in this document which will determine
how much current can be carried as the number of energized contacts is varied.
2. Definitions
DUT – Device Under Test
3. Reference Document s
3.1. EIA-364-70, Temperature Rise Versus Current Test Procedure for Electrical
Connectors and Sockets
3.2. Samtec Document; TLSC 0002, Automated TempRise Software
3.3. Samtec Document; TLWI 0005, Thermocouple Calibration Work Instruction
3.4. Samtec Document; TLOP 0006, Automated Temperature Rise Versus Current
Measurement
3.5. EIA-364-06 Contact Resistance
4. Samples
4.1. Three samples shall be tested for each loading configuration. The DUTs shall be
configured as follows:
4.2. For single row power connectors the following configurations are to be tested:
4.2.1. 1 contact energized only
4.2.2. 2 contacts energized adjacent to each other
4.2.3. 3 contacts energized adjacent to each other
4.2.4. 4 contacts energized adjacent to each other
4.2.5. All contacts energized (list actual number tested)
4.3. For double row power connectors the following configurations are to be tested:
4.3.1. 2x1 contact energized only
4.3.2. 2x2 contacts energized adjacent to each other
4.3.3. 2x3 contacts energized adjacent to each other
4.3.4. 2x4 contacts energized adjacent to each other
4.3.5. All contacts energized (list actual number tested)
4.4. The following defines the sample/thermocouple designations and the data
acquisition channel connections:
4.4.1. 1 contact energized: Samples 1 through 3, connected to Channels 1 - 3
4.4.2. 2 contacts energized: Samples 4 through 6, connected to Channels 4 - 6
4.4.3. 3 contacts energized: Samples 7 through 9, connected to Channels 7 - 9
4.4.4. 4 contacts energized: Samples 10 through 12, connected to Channels 10 -
12
4.4.5. All contacts energized: Samples 13 through 15, connected to Channels 13
– 15
4.4.6. Ambient temp and Wire temp will be monitored on channels 16 and 17
