MIL-PRF-39010E涵盖了既定可靠性（ER）和非既定可靠性（非ER）固定射频模制线圈的一般要求。本规范涵盖的已确定的可靠性射频线圈的故障率水平（FRL）范围为每1000小时1.0%到每1000小时0.001%，在60%的置信水平下确定（见1.2.1.4）。由表III中规定的适用符号标识的FRL指在规定环境温度下满负荷循环条件下的运行。

MIL-PRF-39010E covers the general requirements for established reliability (ER) and nonestablished reliability (non-ER) fixed, radio frequency, molded coils. Established reliability radio frequency coils covered by this specification have failure rate levels (FRL) ranging from 1.0 percent per 1,000 hours to 0.001 percent per 1,000 hours which are established at a 60 percent confidence level (see 1.2.1.4). The FRL identified by the applicable symbol specified in table III refers to operation at full load cyclic condition at the specified ambient temperature.
