RESISTORS, VARIABLE, NONWIRE WOUND (ADJUSTMENT TYPE), GENERAL SPECIFICATION FOR
|Publication Date:||26 November 1993|
This specification covers the general requirements for multiturn lead-screw actuated and single turn nonwire wound, variable resistors with a contact bearing uniformly over the entire surface of the entire resistive element, when positioned by an actuator. These resistors are capable of full load operation (where maximum resistance is engaged) at a maximum ambient temperature of 70°C and 85°C, and are suitable for continuous operation when properly derated, at a maximum temperature of 120°C and 150°C (see figure 1). These resistors have a resistance tolerance of ±10 percent (see 3.1).
The PIN shall be in the following form and as specified herein (see 3.1 and 6.2).
The style is identified by the two letter symbol "RJ" followed by a two-digit number. The letters identify adjustment type, nonwire wound, variable resistors and the number identifies the physical size. Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: 645 LOG/LGME, GENTILE STATION, 1060 HAMILTON street, Dayton, OH 45444-5400 by using the Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.
The characteristic is identified by a single letter in accordance with table
TABLE II. Resistance-temperatu
Nominal resistance −55°C −25°C +25°C +55°C +85°C +125°C
The terminals are identified by a single letter in accordance with table III. TABLE III. Terminals.
Symbol Type of terminal
The nominal resistance value expressed in ohms is identified by a three digit number; the first two digits represent significant figures and the last digit specifies the number of zeros to follow. The following are examples of symbols for resistance values:
101 = 100 ohms 102 = 1,000 ohms 103 = 10,000 ohms 105 = 1 megohm
The PIN RJ24FP103 signifies:
RJ24 - Adjustment type, nonwire wound, variable, resistor of the dimensions specified (see 3.1). F - Having a characteristic signifying a maximum resistance temperature characteristic of 0.010 percent (±100 PPM) per °C, and a capability of operation at rated wattage at 85°C maximum, and when derated, at 150°C maximum (see figure 1). P - Having printed circuit pins. 103 - Having a nominal total resistance value of 10,000 ohms.
