Type CR Electrical Ratings & Dimensions SPECIFY PART NUMBERS AS FOLLOWS: CR __ - __ - __

For example, thepart number for a100watt, 20 ohmunit with standard 18 inch leads isCR100 20. The catalog number for the same resistor with a custom lead length of 36 inches is CR100-20-L36.

Resistance Required Wattage

For special lead lengths, add"L"and the lead length in inches.

RATINGS: The continuous current ratings are based on a 375ºC temperature rise. The resistance values aremeasured at 25ºC and have a + 10% tolerance.
