DIMENSIONS in inches [millimeters]
Notes
(1) On some standard reel pack methods, the leads may be trimmed to a shorter length than shown
(2) L1 max. dimension is clean lead to clean lead
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®
End Caps: Stainless steel
Part Marking: DALE, model, wattage (1), value, tolerance,
date code
Notes
(1) Wattage marked on part will be “U” characteristic
Military (RW) parts are only available with 60/40 Sn/Pb finishc
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.
