MATERIAL SPECIFICATIONS
SPECIAL MODIFICATIONS
Element: Copper-nickel alloy or nickel-chrome alloy,
depending on resistance value
A number of special modifications to the aluminum housed
resistor style are available upon request. Special
modifications include:
Core: Ceramic, steatite or alumina, depending on physical
size
• Terminal configurations and materials
• Resistance values and tolerances
• Low resistance temperature coefficient (RTC)
• Housing configuration
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.
• Threaded mounting holes
• Preconditioning and other additional testing
APPLICABLE MIL SPECIFICATIONS
Vishay RH and NH resistors are listed as qualified on the
MIL-PRF-18546 QPL. MIL-PRF-18546 qualified, type RE
resistors can be found at: www.vishay.com/doc?30282

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 (NH005, for example).
