RS002 Vishay Intertechnology, RS002 Datasheet - Page 2

• Manufacturer Part Number: RS002
• Description: Wirewound Resistors, Military, Mil-prf-26 Qualified, Type RW, Precision Power, Silicone Coated
• Manufacturer: Vishay Intertechnology

DIMENSIONS
*All ∆R figures shown are maximum, based upon testing requirements per MIL-PRF-26.
*On some standard reel pack methods, the leads may be trimmed to
a shorter length than shown.
NOTE: RS-1/8 terminal length will be 1.0" [25.4 mm] minimum.
MATERIAL SPECIFICATIONS
Element: Copper-nickel alloy or nickel-chrome alloy, depending on
resistance value
Core: Ceramic, steatite or alumina, depending on physical size
Coating: Special high temperature silicone
Standard Terminals: 100 % Sn, or 60/40 Sn/Pb coated Copperweld
NOTE: Military "RW" parts are only available with 60/40 Sn/Pb finish.
End Caps: Stainless steel
Deviations for RS-1/8: Thermoset silicone molded construction,
endcaps will be nickel-silver alloy and terminals will be tinned copper
Part Marking: DALE, Model, Wattage*, Value, Tolerance, Date Code
*Wattage marked on part will be "U" characteristic
NS 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 (NS-5, for example).

**B (Max.) dimension is clean lead to clean lead.
Two conditions apply:
1. For NS models, divide maximum resistance values by two
2. Body O.D. on NS-2C may exceed that of the RS-2C by 010"
