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.
