Is it dangerous to take MTTF at face value? The relationship between MTTF and reliability.

The lifespan of a product is a major selection point! Introducing the relationship between product reliability and MTTF.

This document introduces the relationship between product reliability and MTTF (Mean Time to Failure). MTTF is often used as an indicator to understand the lifespan of a product. If the MTTF of a product is known, one can grasp the average lifespan of that product. Additionally, while utilizing MTTF as one of the indicators, it is important to be aware that theoretically, there is approximately a 63% probability of failure occurring before reaching the MTTF. [Contents] ■ Reliability indicating the probability of the product operating ■ Relationship between MTTF and reliability ■ Reference URL *For more details, please refer to the PDF document or feel free to contact us.
