The first type is normal states that the system runs normally, the average time to stay in normal state is MTTF, which is decided by [[lambda].sub.F]; the second type is failure state, the average time to stay in failure state is MTTR, which is decided by XR .
From (6), the product's MTTF under the normal operation stress ([S.sub.0]) can be approximated by using
* Failure rate or failure intensity; these measures are the inverse of MTTF and MTBF.
The most widespread PMs identify the MTTF in steady-state-conditions.
Since failure rates, often described as a mean-time-to-failure (MTTF), increase exponentially with temperature, a 10[degrees]C-increase in temperature can double the failure rate.
The device has an operating lifetime of MTTF 10,000H at 500 mW (at an operating temperature of 25[degrees]C, operating wavelength of 670 nm, optical output power of 500 mW and laser diode reverse voltage of 2 V.
This data indicates that the mean time to failure (MTTF) estimate for the new process is similar to that estimated for the standard process, and the two processes have comparable reliability.
TriQuint continues to demonstrate industry-leading reliability with a mean time to failure (MTTF) of greater than 70 million hours at 200 degrees Celsius, substantially greater than the industry standard of 1 million hours MTTF.
Reliable data is not yet available to determine the junction temperature for a desired mean-time-to-failure (MTTF) for wide bandgap devices, but output power and gain will still degrade with temperature.
As befits data centre storage aimed at cloud computing applications, the MC04ACAxxx hard drives are designed for 24x7 operation and have a mean time to failure (MTTF) rating of 800,000 hours.
Recent work on metamorphic FET device reliability has resulted in excellent results with mean-time-to-failure (MTTF) equal to that of InP FET devices.
Macom s GaN transistor technology has been qualified with accelerated, high-temperature lifetime tests and this device has a predicted Mean Time to Failure (MTTF) of more than 600 years at a maximum junction temperature of 200 degrees Celsius.
