scope:

This specification covers the general requirements for fixed, film, high voltage resistors primarily intended for incorporation into electronic circuits where high voltages and high resistance values are present.

Resistors specified herein shall be identified by a PIN which shall consist of the basic number of the associated detail specification and a coded number. Each associated detail specification covers a different resistor type. The number shall be coded to provide information concerning resistor type, resistance value, and tolerance. The PIN shall be in the following form with a coded number derived as indicated.

The characteristic shall be identified by a single letter A, B, C, and D in accordance with table I.

The style shall be identified by a single letter (see 3.1). The letters available are A, B, C, D, E, F, G, H, J, K, M, and N.

The nominal resistance expressed in ohms is identified by four characters, consisting of three digits and a letter. The letter is used simultaneously as a decimal point and as a multiplier. For resistance values:

a. Greater than or equal to 1 ohm but less than 1 kilohm, the letter "R" is used to represent a decimal point.

b. Greater than or equal to 1 kilohm but less than 1 megohm, the letter "K" is used to represent a decimal point.

c. Greater than or equal to 1 megohm but less than 1 gigohm, the letter "M" is used to represent a decimal point.

d. Greater than or equal to 1 gigohm but less than 1 teraohm, the letter "G" is used to represent a decimal point. Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: U.S. Army Laboratory Command, ATTN: SLCET-R-S, Fort Monmouth, NJ 07703-5000 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

e. Greater than or equal to 1 teraohm, the letter "T" is used to represent a decimal point.

All digits preceding and following the letter (R, K, M, G, T) of the group represent significant figures. The resistance values designations are shown in table II. The minimum and maximum resistance shall be specified herein. The standard values for every decade shall follow the sequence specified in table III.

The resistance tolerance is identified by a single letter in accordance with table IV.
