Notes:
1. Capacity for AWG wires derived from MIL-W-5088B. Maximum ambient temperature: 55°C.
Maximum wire temperature: 105°C.
2. Capacity for metric wires are derived from IE Publication 335-1.
3. Capacity of aluminum wire is approximately 84% of that listed for copper wire.
4. “x” indicates wire is not rated for the maximum output current of the power module.
5. Because of wire inductance considerations, it is also recommended that you keep your load leads
twisted, tie wrapped, or bundled together and less than 50 feet (14.7 meters) in length per lead.
