AMBIENT TEMPERATURE IN °C
Models of equivalent physical and electrical specifications
are available with non-inductive (Ayrton-Perry) winding.
They are identified by inserting the letter N after G in the
model number (GN005, for example). Two conditions apply:
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.
1. For GN models, divide maximum resistance values by two
2. Body O.D. on GN05C may exceed that of the G05C by
0.010"
