Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
