PERFORMANCE SPECIFICATION
RESISTORS, VOLTAGE SENSITIVE (VARISTOR, METAL-OXIDE),
GENERAL SPECIFICATION FOR
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 general requirements for voltage sensitive resistors (varistors) to be used
for suppressing transients in electronic circuitry.
1.2 Classification.
1.2.1 Part or Identifying Number (PIN). The resistors specified herein (see 3.1) are identified by a PIN which
consists of the basic number of the specification and a coded number. The PIN appears in the following form:

1.2.1.1 Nominal voltage. The nominal voltage value expressed in volts is identified by a four digit number; the first
three digits represent significant figures and the last digit specifies the number of zeros to follow.
Examples:
1000
=
100 volts
1001
=
1,000 volts
1002
=
10,000 volts
Minimum and maximum voltage values are as specified (see 3.1). The standard values for every decade follow the
sequence demonstrated for the "10 to 100" decade.
1.2.1.2 Voltage tolerance. The voltage tolerance is identified by a single letter in accordance with table I.
