MILITARY SPECIFICATION

RESISTOR, FIXED, WIRE WOUND (POWER TYPE), STYLES RW80 and RW81

THIS SPECIFICATION IS INACTIVE FOR NEW DESIGN (SEE 6.4)

This specification is approved for use by all Departments and Agencies of the Department of Defense.

1.  SCOPE

1.1  Scope.  This specification covers the associated requirements for styles RW80 and RW81, wirewound inductive resistors.

1.2  Part or Identifying Number (PIN).  Resistors covered by this specification are identified by a PIN, which consists of the style designation, characteristic, and coded resistive value.  The PIN is derived in accordance with MIL-PRF-26 and is in the following form:

Style

(1.2.1)

Characteristic

(1.2.2)

Resistance

(1.2.3)

Resistance

tolerance

(1.2.4)

1.2.1  Style.  The style is identified by the two-letter symbol "RW" followed by a two-digit number.

1.2.2  Characteristic.  The characteristic is identified by a single letter that identifies the maximum continuous operating temperature (surface hot spot), the minimum insulation resistance value at the end of the moisture resistance test, and the resistance temperature characteristic in accordance with table I.

1.2.3  Resistance.  The nominal resistance expressed in ohms is identified by a four-digit number; the first three digits represent significant figures and the last digit specifies the number of zeroes to follow. When resistance values less than 100 ohms are required, the letter "R" is substituted for one of the significant digits to represent the decimal point.  When the letter "R" is used, succeeding digits of the group represent significant figures as shown in the following example.

R100  =   0.1 ohm

1R00  =   1.0 ohm

10R0  = 10.0 ohm
