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 inch from end of resistor body.
