NS NON-INDUCTIVE
Models of equivalent physical and electrical specifications
are available with non-inductive (Aryton-Perry) winding.
They are identified by substituting the letter N for R in the
model number (NS005, for example).
Two conditions apply:
1. For NS models, divide maximum resistance values by two
2. Body O.D. on NS02C may exceed that of the RS02C by
0.010"
