6.0 Electrical Characteristics
6.1 Current Rating - The maximum current rating of the connector is dependent on wire size and
housing/circuit geometry. Figure 1 shows typical graphs of the temperature rise as a function of
current for various wire sizes. Figure1A shows typical graphs of temperature rise as a function of
current for various wire sizes as they were tested in a dense pack (2x36 position) housing. Figure 2
shows temperature rise profiles based on current applied. Charts for Figure 1 and 2 show test results
of PV's that were tested in a single position housing except for 18 and 20 AWG. These are not
recommended for use in a Mini Latch housing.
6.2 Contact Resistance, Low Level - After environmental testing, the change in contact resistance of the
mated connector shall not exceed 2 milliohms when measured in accordance with MIL-STD-1344,
Method 3002. The following details shall apply:
a. Method of Connection - Attach current and voltage leads as shown in Figure 3
b. Test Voltage - 20 millivolts DC max open circuit.
c. Test Current - Not to exceed 100 milliamperes.
6.3 Crimp Resistance, Low Level - When properly crimped, the change in crimp resistance shall not exceed
1 milliohms for wire sizes 18-30 AWG. The change in crimp resistance for 32-36 AWG shall not exceed
2 milliohms. Crimp resistance shall be measured in accordance with MIL-STD-1344, Method 3002. The
following details shall apply:
a. Method of Connection - Attach current and voltage leads as shown in Figure 3A.
b. Test Voltage - 20 millivolts DC max open circuit.
c. Test Current - Not to exceed 100 milliamperes.
6.4 Insulation Resistance - The insulation resistance of unmated terminals, properly mounted in Mini-Latch
housings, shall not be less than 10,000 megohms ( 5000 megohms after exposure to the humidity
environment described below) when measured in accordance with MIL-STD-202,Method 302. The
following details shall apply:
a. Test Voltage - 500 volts DC
b. Electrification Time - 2 minutes
c. Points of Measurement - Between adjacent and opposing contacts.
