Reference topics covering thermal qualification, MTBF, derating and capacitor lifetime.
Real-load temperature profiling and hotspot identification can reveal whether critical components operate within appropriate thermal margins.
Calculated reliability models can be complemented by accelerated-life evaluation where appropriate.
Review voltage, current, power and temperature stress against recommended limits to identify components with limited operating margin.
Operating ripple current and temperature have a direct bearing on capacitor lifetime; the customer's baseline calls for Arrhenius-based lifetime modelling and individual capacitor analysis.
