GN NON-INDUCTIVE

Models of equivalent physical and electrical specifications are

available with non-inductive (Aryton-Perry) winding. They are

identified by inserting the letter N after G in the model number

(GN-5, for example). Two conditions apply:

100

1. For GN models, divide maximum resistance values by two

2. Body O.D. on GN-5C may exceed that of the G-5C by 0.010"

CHAR. V

TERMINATION

CHAR. U

When G resistors will be operated at full rated power,

resistance welding or high temperature solder are the

recommended termination methods. Termination should be

made within 1/2 inch from end of resistor body.
