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  
80  
60  
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  
20  
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.
