2.11.1 Annualized Failure Rate (AFR)
The product will achieve an Annualized Failure Rate (AFR) of 0.55% when operated in an environment of ambient air
temperatures of 25°C. Operation at temperatures outside the specifications in
increase the product AFR. AFR is a population statistics that is not relevant to individual units.
AFR specifications are based on the following assumptions for consumer electronics environments:
• 8760 power-on-hours per year
• 10,000 average motor start/stop cycles per year
• Operations at nominal voltages
• Temperatures outside the specifications in
• Normal I/O duty cycle for consumer electronics environments. Operation at excessive I/O duty cycle may degrade
product reliability.
The consumer electronics environment of power-on-hours, temperature, and I/O duty cycle affect the product AFR. The AFR
will be degraded if used in a enterprise application
