Therefore, the tests and inspections herein may not be performed for the applicable device class (see MIL-PRF-38534). The manufacturer may eliminate, modify or optimize the tests and inspections herein, however the
21、 performance requirements as defined in MIL-PRF-38534 shall be met for the applicable device class. In addition, the modification in the QM plan shall not affect the form, fit, or function of the device for the applicable device class. 1/ Stresses above the absolute maximum ratings may cause permane
22、nt damage to the device. Extended operation at the maximum levels may degrade performance and affect reliability. 2/ For operation at temperatures between +85C and +125C, derate the maximum input voltage linearly from 60 V dc to 40 V dc and the maximum output power from 100% to 75%. 3/ Derate output
23、 power linearly above case temperature +125C to 0 at +135C. 4/ Limit represents 80% of total rated output current.
