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 Section 3.6, Environmental Specifications may
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 Section 3.6, Environmental Specifications may reduce the product reliability.
•
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.
