2.3  Order of precedence.  In event of a conflict between the text of this document and the references cited herein (except for related associated specifications, specification sheets, or MS sheets), the text of this document takes precedence.  Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained.

3.  REQUIREMENTS

3.1  General.  The requirements for acquiring the product described herein shall consist of this document and

MIL-PRF-55182.

3.2  Interface and physical dimensions.  The resistors shall meet the interface and physical dimensions specified in figure 1.

*         3.2.1  Characteristics.  Style RN*56 is available in characteristics H, J, and K.  1/

*         3.2.2  Terminal types.  Terminal type RNR is inactive for new design with characteristics H, J, and K.

3.3  Power rating.  The power rating shall be 0.100 watt, based on full load operation at an ambient temperature of

125oC (see 6.4).

3.4  Voltage rating.  The continuous working voltage shall not exceed 200 volts.

3.5  Resistance.  The resistance values shall be 10 ohms minimum to 1.210 megohms maximum for characteristics

H, J, and K.

3.6  Voltage coefficient (applicable to resistors of 1,000  ohms and above).  The voltage coefficient shall not exceed

±0.005 percent per volt.

3.7  Mechanical sheer.  Mechanical sheer is required for this style resistor.

3.8  Insulation.  Insulating material surrounding the resistor body shall extend around the entire shoulder of each end cap toward the axis of the lead attachment.

3.9  Marking.  Due to size limitations this style resistor shall be marked with the following minimum information:

226K                    Date code, characteristic

24R9                    Coded resistance

FMCJ                   Tolerance, failure rate, terminal type and JAN marking

1/  Third letter is variable, dependent upon lead material or capability.
