PERFORMANCE SPECIFICATION
RESISTOR, FIXED, METER MULTIPLIER, EXTERNAL
(HIGH VOLTAGE, FERRULE TERMINAL TYPE)
This specification is approved by all Departments
and Agencies of the Department of Defense.
1. SCOPE
1.1 Scope. This specification covers the requirements for high-voltage, external, meter-multiplier, fixed resistors of
the ferrule-terminal type for use with direct-current (dc) instruments drawing 1 milliampere at full-scale deflection.
Designers are CAUTIONED on using these resistors in pulse applications (see
6.5).
1.2 Classification.
1.2.1 Part or Identifying Number (PIN). The PIN must be in the following form and as specified (see 3.1
).
1.2.1.1 Style. The style is identified by a three-letter symbol. The first two letters, MF, identify high voltage,
external, meter-multiplier, fixed resistors of the ferrule-terminal type. The third letter identifies the particular physical
dimensions.
1.2.1.2 Resistance. The nominal resistance in ohms is designated by a three-digit number. The first two digits
represent the first two significant figures of the figures of the resistance value, the third digit indicates the number of
zeros to follow.
1.2.1.2.1 Resistance range. Resistors have a resistance range of 0.5 ohm to 20 megohms.
