Aluminum Case resistors are available in three(3) standard sizes rated between 50 to 5000 continuous watts per assembly. The overall size of the case determines the wattage rating and can be varied to meet specific ratings. Units can be customized to any resistance value within the resistance ranges from 1 ohm to 10kohm.

Leads
The standard lead length is 300mm, which could be customized as per required.

Voltage Insulation
A standard Aluminum Case resistor is insulated for up to 3500 volts maximum.

Temperature
Standard ratings are based on ambient temperatures of 25°C, with a 150°C rise maximum. The bigger size, the lower temperature rise.
