Symbol for the prefix nano, or one billionth.
A large radio frequency connector covered by military specification.
An input/output connector with threaded couplings. N-type connectors are commonly used in microwave systems.
The preferred term for shrounded header.
See Header.
A logic gate that is equivalent to an AND gate followed by a NOT gate. If both inputs are 1, its output is 0; otherwise its output is 1. All Boolean logic operations can be built out of NAND gates.
Prefix meaning one billionth or one thousandth of one millionth.
A unit of measure equal to one billionth of a meter.
A set of guidelines for the installation of electrical wiring and apparatus. Sponsored by the National Fire Protection Association under the auspices of the American National Standards Institute (ANSI).
Nitrile-butadiene rubber or, alternatively, butadiene-acrylonitrile copolymer rubber. A material with good oil and chemical resistance.
A blend of nitrile rubber and polyvinyl chloride.
See Numerical Control.
The backward noise (or noise which flows toward the generator or near end of the line) resulting from an active line being too close to a victim line where the former's electric and magnetic field coupling creates this noise as a function of signal voltage amplitude, coupling length (up to a max for NEN saturation to occur), and its relative coupling coefficients.

The official point of demarcation between a local telephone company network and the premises wiring system. This may differ slightly from the building entry point.
Ground. The common or grounded wire in a single or three-phase power cable.
Near End Crosstalk
See Crosstalk.
One half byte, or 4 bits.
A small cut or notch in conductor strands or insulation.
Metallic element with atomic # 28. High purity nickel is used for applications in which copper normally would be used, but where high temperatures are likely.
Non-metallic sheathed cable. Braid or plastic covered, 60° C.
Non-metallic sheathed cable. Plastic or neoprene covered, 60° C.
Non-Optical Disconnect, feature prevents ferrules from separating when force is applied to the cable.
Non-Accum
Non-accumulative
Non-compliant Press-fit Technology
A square pin pushed into a slightly undersized plated through hole on a PCB.
See also Compliant Pin Press-fit Technology.
A compounded material that will not leach ingredients and contaminate or degrade adjacent materials.
A land on internal or external layers, not connected to the conductive pattern on its layer.
Solderless terminals without insulation.
A condition in which the terminals, in their normal state, are not stressed.
Non-zero Insertion Force (Non-ZIF)
A characteristic of a connector that differentiates it from Zero Insertion Force (ZIF) connectors, such that the insertion of flat flexible cable or flexible printed circuitry results in a discernible amount of insertion force.
In membrane switch technology, a micro motion single-pole, single-throw switch that does not have mechanical snap when depressed.
A condition in which a surface has contacted molten solder, but none of the solder has adhered to it.
A Boolean logic gate used in computer arithmetic. The OR gate output is 0 if either or both of its inputs is 1; it is equivalent to an OR gate followed by a NOT gate. An exclusive NOR gate has an output of 1 if both inputs are the same.
The force perpendicular to the contact interface.
In a switch or relay, the contact pairs that are closed when the switch is not held on or the relay is not energized (no coil current), and open when the relay is energized, or in the case of the switch, open when the switch is held on.
In a switch or relay, the contact pairs that are open when the switch is not held on or relay is not energized (no coil current), and closed when the relay is energized, or in the case of the switch, closed when the switch is held on.

Nippon Television and Telegraph Advances Technology
A contact with a locking member that remains in the insert at all times.
In fiber optics, a characteristic parameter that defines the angles at which a component such as a fiber will accept light or the angles at which light will exit the component. Also it indirectly controls the number of transmission modes that the fiber can support.
