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: 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"
TERMINATION
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" from end of resistor body.
