WebQuality and reliability data provided by TI, such as MTBF and fit rate data, is intended to facilitate an estimate of the part’s performance to spec, based solely on the part’s historical observations. It should not be interpreted that any performance levels reflected in such data can be met if the part is operated outside appropriate ... Failure rate is the frequency with which an engineered system or component fails, expressed in failures per unit of time. It is usually denoted by the Greek letter λ (lambda) and is often used in reliability engineering. The failure rate of a system usually depends on time, with the rate varying over the life cycle of the system.
