MATERIAL SPECIFICATIONS
Element: Copper-nickel alloy or nickel-chrome alloy,
depending on resistance value
Core: Ceramic, Beryllium oxide or alumina, depending on
resistor model
Coating: Special high temperature silicone
Standard Terminals: 100 % Sn, or 60/40 Sn/Pb coated
Copperweld®
NOTE: Military (RW) parts are only available with 60/40
Sn/Pb finish
End Caps: Stainless steel
Part Marking: DALE, Model, Wattage*, Value, Tolerance,

* Wattage marked on part will be "U" characteristic
** L1 (Max.) dimension is clean lead to clean lead.
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.
