+## Mean Time Between Failure (MTBF)
+
+MTBF, which stands for Mean Time Between Failure, is calculated according to statistical device failures and indicates the reliability of a device.
+
+The MTBF figure (in hours/years) for each Arduino Opta® variant can be found in the table below. The MTBF figure was calculated according to the MIL-HDBK-217F parts count method.
+
+|  **Standard** | **All Opta® Variants** | **Environmental Conditions** |
+|:-------------:|:----------------------:|:----------------------------:|
+| MIL-HDBK-217F |    766205 h/87 years   |             25 ºC            |
+
+**Important note**: MTBF is the statistical representation of the likelihood of a unit failing and _does not necessarily represent a product's life_.
