The VS-720 family is capable of meeting the following qualification tests: Environmental Compliance Parameter Mechanical Shock Mechanical Vibration Solderability Gross and Fine Leak Resistance to Solvents Conditions MIL-STD-883, Method 2002 MIL-STD-883, Method 2007 MIL-STD-883, Method 2003 MIL-STD-883, Method 1014 MIL-STD-883, Method 2016 Handling Precautions Although ESD protection circuitry has been designed into the VS-720 proper precautions should be taken when handling and mounting. VI employs a human body model (HBM) and a Man Man method (MM) for ESD susceptibility testing and design protection evaluation.
