Operational DMD temperature and landed duty cycle interact to affect DMD useful life, and this interaction can be exploited to reduce the impact that an asymmetrical landed duty cycle has on the DMD useful life. This is quantified in the de-rating curve shown in Figure 1. The importance of this curve is that:
In practice, this curve specifies the maximum operating DMD temperature for a given long-term average landed duty cycle.
