Test show connectors operate at increased current
Test show a temperature rise of 30°C for current up to 8.5 A per pin.
How do the military and aerospace use MBSE?
Model-based systems engineering (MBSE) is broadly defined as the structured use of digital modeling to support system features, requirements, design, verification, and validation extending from the conceptual design phase and continuing until end of life. The concept of systems engineering is deeply engrained in the military and aerospace communities. MBSE represents a shift from highly […]
