Reliability - Mean Time Between Failure
The product will achieve a Mean Time Between Failure (MTBF) of 1,000,000 hours when operated in an
environment of ambient air temperatures of 25°C. Operation at temperatures outside the specifications shown in
Section 2.9
may increase the product MTBF. MTBF is a population statistics that is not relevant to individual units.
MTBF 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
MTBF. The MTBF will be degraded if used in an enterprise application.
