This specification covers fixed, hermetically sealed resistors of high resistance values. These resistors have a resistance range of l08 to 1013 ohms, inclusive, with a resistance tolerance of 5 percent at 25°C and are capable of operation at 70°C. These resistors are not intended for use in equipment where vibration resistance is a requirement.

The type designation of resistors shall be in the following form, and as specified (see 3.1 and 6.1): CHART

The style is identified by the two-letter symbol "RM" followed by a two-digit number; the letters identify fixed, hermetically sealed resistors of high resistance value and the number identifies the size of the resistor.

The characteristic is identified by a single letter in accordance with table I. TABLE I.  Characteristic

The nominal resistance value expressed in ohms is identified by a four-digit number. The first two digits indicate the multiplier and the last two digits indicate the exponent. A decimal point after the first digit is to be assumed, for example, 2408 == 2.4 x 108; 1013 = 1.0 x 1013.

Resistance values per decade shall be inaccordance with table II, which shows the values in 108 range. TABLE II. Resistance values for 1 to 10 decade in the 108 range
