An insulator that is essentially thin, flat, and round in shape, with or without holes. The general shape may vary by the addition of such features as beveled edges, indented surfaces, through-hole key and/or peripheral flats. It may have one or more holes off center; if there are two or more holes, one may be centrally located. Excludes mounting pad, electrical-electronic component.
Indicates there is no information in the hmirs. The nsn is in a fsc in table ii of fed std 313 and a msds may be required by the user. The requirement for a msds is dependent on a hazard determination of the supplier or the intended end use of item.
Item does not contain precious metal.
No known electrostatic discharge (esd) or electromagnetic interference (emi) sensitivity.
Represents items with no adp components
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.
