A grouping of two or more semiconducting devices such as light emitting diode; semiconductor device, diode; semiconductor device, photo; semiconductor device, thyristor; and/or transistor mounted on a common mounting or mounted on each other. The devices must be separable and each item must be capable of functioning in accordance with its given name. For assemblies consisting of semiconducting devices permanently cased, encapsulated, or potted together to form a single unit, see rectifier, semiconductor device, unitized and semiconductor devices, unitized. Excludes semiconductor device set; microcircuit assembly; and microcircuit set. See also absorber, overvoltage.
Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.
Item does not contain precious metal.
Represents items with esd sensitivity.
Represents items with no adp components
The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
HMIC: Hazardous Material Indicator Code. Identifies a hazardous item.
PMIC: Precious Metal Indicator Code. Identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.
ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.
ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.
CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.
