Shielded RoomA room made free from EMI by applying shielding to the floor, walls, and ceiling, and by suppressing interference entering through the power lines. Typical construction shields from 70 dB to 140 dB from 10 kHz to 10 GHz.
Shielding EffectivenessMeasured using plane waves in the far field (relatively far from the radiating antenna).
Signal IntegrityA set of measures of the quality of an electrical signal.
SIA set of measures of the quality of an electrical signal.
Skin Effectthe tendency of an alternating electric current (AC) to become distributed within a conductor such that the current density is largest near the surface of the conductor, and decreases with greater depths in the conductor
Standards BodiesAny organization whose primary activities are developing, coordinating, promulgating, revising, amending, reissuing, interpreting, or otherwise producing technical standards that are intended to address the needs of some relatively wide base of affected adopters.
SusceptibilityA measure of how easily a dielectric polarizes in response to an external electric field.
Switch Mode Power SupplyAn electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
TemperatureA numerical measure of hot or cold. Its measurement is by detection of heat radiation or particle velocity or kinetic energy, or by the bulk behavior of athermometric material.
TerahertzA unit of measure of frequency that is equal to 1 trillion hertz (1012 Hz)
THzA unit of measure of frequency that is equal to 1 trillion hertz (1012 Hz)
TeslaUnit of magnetic field strength or magnetic flux density, commonly denoted as B. One tesla is equal to one weber per square meter.
ThermistorA type of resistor whose resistance varies significantly with temperature, more so than in standard resistors.
ThermocoupleA temperature-measuring device consisting of two dissimilar conductors that contact each other at one or more spots.
Through-hole Technology / Thru-Hole TechnologyRefers to the mounting scheme used for electronic components that involves the use of leads on the components that are inserted into holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side either by manual assembly (hand placement) or by the use of automated(...)
TIA-4950The purpose of this standard is to provide requirements for the construction and testing of electrical apparatus, or parts of such apparatus, having circuits that are not capable of causing ignition in Division 1 hazardous locations as defined in Article 500.5 of the National Electrical(...)
TransducerA transducer is an electronic device that converts one form of energy to another.
TransformerA static electrical device that transfers energy by inductive coupling between its winding circuits.
TransientA high amplitude, short-duration sound at the beginning of a waveform that occurs in phenomena such as musical sounds, noises or speech.
TransistorA semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit.
