Specification
Expose parts to an environment of +50°C with 90 to 95% R.H. for 100
hours. After exposure, allow parts to dry for 2 hours before measurements
are taken.
Subject parts to an environment of +50°C 90 to 100% R.H. for 46 to 50
hours. After exposure, allow parts to dry for 2 hours before measurements
are taken.
Per MIL-STD 202 Method 106, ten 24 hour cycles at +25°C to
+65°C at 80 to 95% R.H. During any of the first 9 cycles, inductors
are revolved from the chamber and exposed to -10°C for 3 hours.
Allow parts to dry for 2 hours before measurements are taken.
10 cycles (Air to Air) 1 cycle shall consist of:
30 minutes exposure to +85°C
30 minutes exposure to -40°C
Allow 20 minutes transition between extremes.
10 cycles (Air to Air) 1 cycle shall consist of:
30 minutes exposure to -45°C
30 minutes exposure to +125°C
15 seconds maximum transition between temperatures
Withstands needle-flame test
Inductors shall be randomly vibrated per NAVMAT P9492
profile. Samples shall be subjected to 0.04G/Hz for a
minimum of 15 minutes per axis, for each of the three axes.
Test per MIL-STD 202 method 213 test condition A, test
mounted samples 3 axes, 6 times, totaling 18 shocks.
(50Gs, 11ms, half-sine).
Dip pads in RMA flux, 63/37 solder (Sn/Pb) at 232°C for 5 seconds ±2
seconds.
Apply and measure force with a digital force gauge set.
