ENVIRONMENTAL SPECIFICATIONS
Temperature Cycle:
400 cycles from –55°C to +125°C, 10 minute dwell at each temperature, 1
minute transfer time between temperatures.
Mechanical Shock:
1,500g’s, 0.5mS duration, ½ sinewave, 3 shocks each direction along 3
mutually perpendicular planes (18 total shocks).
Sinusoidal Vibration:
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).
Gross Leak:
No leak shall appear while immersed in an FC40 or equivalent liquid at
+125°C for 20 seconds.
Fine Leak:
Mass spectrometer leak rates less than 2x10-8 ATM cc/sec air equivalent.
Resistance to Solder Heat:
Product must survive 3 reflows of +260°C peak, 10 seconds maximum.
High Temperature Operating Bias:
2,000 hours at +125°C, maximum bias, disregarding frequency shift.
Frequency Aging:
1,000 hours at +85°C, full bias, less than ±5 ppm shift.
QUALITY AND RELIABILITY
Quality systems meet or exceed the requirements of ISO 9000:2000 standards. Reliability audits are performed on
this or similar products with results available upon request.
