Design Philosophy
Ruggedization Capabilities
Mission critical applications require that certain product design considerations - thermal, vibration, and temperature - are a priority from inception, not after-the-fact. BittWare prides itself on its expertise and ability to architect and design extended temperature/ruggedized products for military/defense applications. In no instance is a commercial product simply modified for implementation in a rugged application.
The ruggedization levels provided in the chart below show maximum values and should be used as guidelines.
