Fit Calculator

Vishay's FIT calculator program was developed to follow the calculations defined in MIL-HDBK-217 (revision F). This FIT calculator program enables users to predict the reliability of tantalum capacitors. Vishay customers can input information about applications, ambient temperature, operating voltage, and environmental factors to create multipliers of established failure rates for many military tantalum capacitors types.

Using factory-monitored reliability of the non-military, commercial part types, these multipliers will define a projected application failure rate The failure rates are listed as "FIT" (failures in time) and "MTBF" (mean time between failures).

For the specific Vishay tantalum capacitors contained within the FIT calculator program, theprogram's unique characteristics enable instantaneous results and provide important design-related information.
