Derating is required for ambient temperatures above 25 °C, see the following graph.

Curves A, B, C apply to operation of unmounted resistors. Curve D applies to all types when mounted to specified heat sink.

A = RH-5 and RH-10 size resistor, unmounted

B = RH-25 size resistor, unmounted

C = RH-50, RH-100 and RH-250 size resistor, unmounted

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 RH-5 through RH-50 size terminal

finish - Tin/lead is 60/40 Sn/Pb w/Nickel underplate & Lead

(Pb)-free is Ni/Pd/Au, finish is on copper clad steel core

terminal. For RH-100 & RH-250 terminals are threaded

stainless steel.

• Threaded mounting holes

• Preconditioning and other additional testing

Note: Military (RE) parts are only available with tin/lead finish

APPLICABLE MIL SPECIFICATIONS

Part Marking: DALE, Model, Wattage, Value, Tolerance,

Date Code

MIL-PRF-18546 is the military specification covering

aluminum housed, chassis mount, power resistors. VISHAY

RH and NH resistors are listed as qualified on the

MIL-PRF-18546 QPL.

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).
