FIT Rate / MTBF Calculator

FIT/MTBF Calculator | Back to Development Calculators

This calculator estimates the FIT rate and MTBF for SiTime products under specific operating conditions.

What is FIT Rate?

FIT stands for Failure in Time and indicates the frequency at which a system component fails every 1000000000 hours. It is an important statistic when considering a device's reliability over the years and is directly related to MTBF. MTBF stands for Mean Time between Failure, which estimates the average time one can expect a system to function between failures during normal operating conditions.
