II-VI Marlow has an ongoing reliability program, with TECs operating at constant current and constant hot side temperatures (aging tests).

The TECs are periodically removed for performance tests, and the change in performance assessed. The rate of change with time and temperature has been modeled. These models are then used for the calculation of hazard rates, or FITS.

Given a defined life (typical is 20 years), an operating temperature (typically 40 or 50°C), and definition of failure (typically expressed as a percent change in voltage), II-VI Marlow can provide a FIT rate. Please contact one of II-VI Marlow’s engineers for your specific reliability questions or FIT calculation needs.
