• Manufacturer: VISHAY [Vishay Siliconix]

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 RH-5 through RH-50 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 RH-100 and RH-250 terminals are threaded
stainless steel.
Note:
Military (RE) parts are only available with tin/lead finish
Part Marking: DALE, model, wattage, value, tolerance, date
code
NH 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 (NH-5, for example).
