ENVIRONMENTAL SPECIFICATIONS
Temperature Cycle: Mechanical Shock: Sinusoidal Vibration: Gross Leak: Fine Leak: Resistance to Solder Heat: High Temperature Operating Bias: Frequency Aging: 400 cycles from -55C to +125C, 10 minute dwell at each temperature, 1 minute transfer time between temperatures. 1,500g's, 0.5mS duration, 1/2 sinewave, 3 shocks each direction along 3 mutually perpendicular planes (18 total shocks). 0.06 inches double amplitude, 10 to 55 Hz and 20g's, 55 to 2,000 Hz, 3 cycles each in 3 mutually perpendicular planes (9 times total). No leak shall appear while immersed in an FC40 or equivalent liquid at +125C for 20 seconds. Mass spectrometer leak rates less than 2x10-8 ATM cc/sec air equivalent. Product must survive 3 reflows of +260C peak, 10 seconds maximum. 2,000 hours at +125C, maximum bias, disregarding frequency shift. 1,000 hours at +85C, full bias, less than 5 ppm shift.
