MIL MIL-PRF-39007J涵盖了电气、电子通信和相关设备中使用的非确定可靠性（non ER）、确定可靠性（ER）或空间级、轴向引线精度、功率型、绕线式、固定电阻器的一般要求，该电阻器的环境工作温度为+25℃，在+250℃时降额为零负载。这些电阻器的初始电阻公差为±.5%，±.1%和±1%，电阻温度特性如表I所示。本规范所涵盖的ER电阻器的故障率（FR）范围为1%到1%。每1000小时001%（见1.2.1.5）。根据寿命试验（允许的电阻变化为1.0%），在60%的置信度下确定这些FR。非感应式绕有可焊端子的电阻器由指定为“N”和“Z”的端子指定。字母“S”和“W”指定的端子采用可焊接和可焊接端子感应式绕线。

MIL MIL-PRF-39007J covers the general requirements for nonestablished reliability (non-ER), established reliability (ER), or space level, axial lead precision, power type, wire wound, fixed resistors having a +25 C ambient operating temperature derated to zero load at +250 C for use in electrical, electronic communication, and associated equipment. These resistors have initial resistance tolerances of ±.5 percent, ±.1 percent, and ±1 percent, and a resistance temperature characteristic as given in table I. ER resistors covered by this specification will have failure rates (FR) ranging from 1 percent to.001 percent per 1,000 hours (see 1.2.1.5). These FR are established at 60 percent confidence on the basis of life tests (permissible resistance change of 1.0 percent). Resistors which are noninductively wound with solderable terminals are designated by a terminal designated "N" and "Z". Terminals designated by the letters "S" and "W" are inductively wound with solderable and weldable terminals.
