MATERIAL SPECIFICATIONS
Element: Copper-nickel alloy or nickel-chrome alloy,
depending on resistance value
Core: Ceramic, steatite or alumina, depending on physical
size
Encapsulant: Silicone molded construction
Housing: Aluminum with hard anodic coating
End Caps: Stainless steel
Standard Terminals: For RH005 through RH050 size
terminal finish - Tin/lead is 60/40 Sn/Pb w/Nickel underplate
and Lead (Pb)-free is Ni/Pd/Au, finish is on copper clad
steel core terminal. For RH100 and RH250 terminals are
threaded stainless steel.
Part Marking: Dale, model, wattage, value, tolerance, date
code
NH NON-INDUCTIVE
Models of equivalent physical and electrical specifications
are available with non-inductive (Ayrton-Perry) winding.
They are identified by substituting the letter N for R in the
model number (NH005, for example).
