Definition Definition of approved item name (AIN): "RESISTOR,FIXED,COMPOSITION"

A resistor whose ohmic value cannot be adjusted or varied. The resistance element consists of a mixture of carbon, an insulating material, and suitable binders, either molded together or applied as a thin layer of conducting material on an insulated form. The opposition to the flow of current is an inherent property of the materials used and is manifest by the heat dissipation in the item itself. See also attenuator, fixed; resistor, fixed, film; and resistor, thermal. Excludes suppressor, ignition interference.

Hazmat (HMIC) N

Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.

Precious Metals (PMIC) A

Item does not contain precious metal.

Electrostatic Discharge (ESD) B

Represents items with esd sensitivity.

ADPE 0

Represents items with no adp components

Criticality X

The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.

  Identification Codes

HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.

PMIC: Precious Metal Indicator Code. A one position code which 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.

  Material Codes

SOS: Source of Supply. A three position code or routing identifier code (ric), which identifies the source of supply activity.

SMIC: Special Material Indicator Code. A two position code, which categorizes material on the basis of requirements for source or quality control, technical design or configuration control, procurement, stocking and issue control, special receipt, inspection, testing, storage, or handling.

MMAC: Material Management Aggregation Code. A two position code that identifies an item of supply to be managed by a specific activity manager.

MCC: Material Echelon Code. A two position code employed by the marine corps in classifying items into categories by materiel category and procurement echelon. the alphanumeric management code is in the first position and identifies the materiel category

IMC: Denotes wether items shall be subjected to integrated management under the defense supply agency or retained by the individual military service or other department of defense components for their management. Assigned by th activity responsible for item management coding.
