تعريف dielectric في الإنجليزية الإنجليزية القاموس.
An electrically insulating or nonconducting material considered for its electric susceptibility, i.e. its property of polarization when exposed to an external electric field
A material that conducts no current when it has voltage applied to it Two dielectrics used in semiconductor processing are silicon dioxide and silicon nitride
1) any insulating medium which intervenes between two conduits and permits electrostatic attraction or repulsion to take place across it 2) a material having the property that energy required to establish an electric field is recoverable in whole or in part, as electric energy (see insulation for clarification)

{s} of or pertaining to a dielectric substance, of or pertaining to a material that does not conduct electricity
Material that does not conduct electricity Generally used for making capacitors, insulating conductors (as in crossover and multilayered circuits) and for encapsulating circuits
Nonmetallic All-dielectric designs are inherently nonconductive; all-dielectric cables contain no metal and are lightning resistant
Insulating material or a very poor conductor of electric current. Dielectrics have no loosely bound electrons, and so no current flows through them. When they are placed in an electric field, the positive and negative charges within the dielectric are displaced minutely in opposite directions, which reduces the electric field within the dielectric. Examples of dielectrics include glass, plastics, and ceramics
A material typically used as an insulator that contains few (if any) free electrons, has low electrical conductivity and supports electrostatic stresses
An insulator occupying the space between two conductors such as the inner and outer conductors of coaxial cable
material is a substance that is a poor conductor of electricity, but an efficient supporter of electrostatic fields
A nonconducting or insulating substance that resists passage of electric current
Any substance or medium that transmits the electric force by a process different from conduction, as in the phenomena of induction; a nonconductor
The nonconducting material used to separate conducting materials New copper/low-k interconnects have shown to improve circuit density, speed, reliability, and reduce interconnect cross-talk
A material that is nonmetallic and non-conductive Generally used to describe the insulating material surrounding the center conductor of a coaxial cable
A nonconducting or insulating material that prevents passage of electric current and resists inductive coupling
An insulator Localized regions of dielectric materials are used in semiconductor devices to provide electrical isolation between dice, between metal interconnect layers, and between the gate electrode and the channel
The voltage potential at which the insulating properties of a non-conductor will break down and conduct current Measured in kilo-volts Direct Current (DC) An electric current flowing in one direction (constant polarity) as opposed to Alternating Current which periodically changes polarity Double Pole Double Throw (DPDT, 2 form C contacts) A type of contact configuration which consists of two isolated sets of contacts operating simultaneously Each contact set consists of a: Common contact, Normally Open contact and a Normally Closed contact In relay nomenclature, the states of the contacts are given with the relay coil unenergized
Any change in the properties of a dielectric that causes it to become conductive; normally a catastrophic failure of an insulation because of excessive voltage
Any change in the properties of a dielectric that causes it to become conductive Normally a catastrophic failure of an insulation because of excessive voltage
Any change in the properties of a dielectric that cause it to become conductive Normally a catastrophic failure of insulation because of excessive voltage
Any change in the properties of a dielectric that cause it to become conductive Normally a catastrophic failure of an insulation because of excessive voltage
The dielectric regions within a semiconductor have a unique breakdown voltage associated with them When an applied voltage, such as an ESD pulse, exceeds this voltage, a dielectric puncture can occur Depending upon the amount of pulse energy, the puncture may fuse and the device may either exhibit a reduced breakdown voltage; an increased leakage current (both possible parametric failures); or fail completely See Failure Mechanism
The property of a dielectric which determines the amount of electrostatic energy that can be stored by the material when a given voltage is applied to it Also called permattivity
The ratio of the capacity of a condenser having a dielectric constant between the plates to that of the same condenser when the dielectric is replaced by a vacuum; a measure of the electrical charge stored per unit volume at unit potential
The ratio of the capacity of a condenser (made with a dielectric material) to the capacity of the same condenser (with air as the dielectric) Measured at a frequency of 10E6 cycles per second
For a given substance, the ratio of the capacity of a condenser with that substance as dielectric to the capacity of the same condenser with a vacuum for dielectric It is a measure, therefore, of the amount of electrical charge a given substance can withstand at a given electric field strength; it should not be confused with dielectric strength
Also called permitivity That property of a dielectric which determines the amount of electrostatic energy that can be stored by the material when a given voltage is applied to it Example: the ratio of capacitance of a capacitor using the dielectric to the capacitance of an identical capacitor using a vacuum as a dielectric
A parameter characterzing the relative ability of a dielectric material in a capacitor to produce energy storage The higher the number the better the capacitor
The specific inductive capacity of a dielectric That property of a dielectric which determines the electrostatic energy stored per unit volume for unit potential gradient The dielectric constant of a medium is defined by e in the equation F = QQ1/er2 , where F is the force of attraction between two charges Q and Q1 separated by a distance r in a uniform medium
The term used to describe a material's ability to store charge when used as a capacitor dielectric It is the ratio of the charge that would be stored with free space to that stored with the material in question as the dielectric
That property (K) of an insulating material which is the ratio of the parallel capacitance (C) of a given configuration of electrodes with the material as the dielectric, to the capacitance of the same electrode configuration with a vacuum as the dielectric
The dielectric constant of a material (wood) is the ratio of the electric potential energy stored in a certain volume of the material in a given electric field to the corresponding energy stored in the same volume of free space in the same electric field
Also called permittivity That property of a dielectric which determines the amount of electrostatic energy that can be stored by the material when a given voltage is applied to it Actually, the ratio of the capacitance of a capacitor using the dielectric to the capacitance of an identical capacitor using a vacuum as a dielectric
