What is the lifetime in hours for DS90UB948TNKDRQ1?

If the IC is continuously working 24 hours every day, besides high risk to longevity, are there any other side effects?

Hi TzuYang,

TI reliability has a resource page to help you get specifics on the reliability of this part and package.

Please input the device P/N and package type into the MTBF/FIT estimator found at this: https://www.ti.com/quality/docs/estimator.tsp.

Hi Esther

The Fit rate for DS90UB948TNKDRQ1 is 1.3, then converting FIT to MTTF is 87811 years.

That means DS90UB948TNKDRQ1 can continuously working 24 hours every day for 87811 years?

Hi Derek,

The MTBF is the theoretical time on average before failure, so that would be 7.93e8 hours, or ~90000 years, but since it is an average, theoretical, and dependent on testing conditions, it won't be that accurate.

Best,

Esther
