Abbreviation for volt.
Abbreviation for volt-ampere.
Combination of Variable Resistor. A two-electrode semiconductor device having a non-linear, voltage-dependent resistance (usually a high resistance at low voltages and low resistance at high voltages). Often used to protect circuits against transient voltages.
The process of dipping a transformer or coil in varnish to bind or protect materials.
Voltage Collector Collector. Positive supply voltage of a Bipolar Junction Transistor. The doubled suffix indicates that the voltage is common. i.e. it is the supply voltage to one (or more) collectors and not just the voltage at a specific collector.
Voltage Drain Drain. Positive supply voltage of a Field Effect Transistor. The doubled suffix indicates that the voltage is common. i.e. it is the supply voltage to one (or more) drains and not just the voltage at a specific drain.
Abbreviation for Verband Deutscher Elektrotechniker.
Abbreviation for Voltage Dependent Resistor.
Voltage Emitter Emitter. Negative supply voltage of a Bipolar Junction Transistor. The doubled suffix indicates that the voltage is common. i.e. it is the supply voltage to one (or more) emitters and not just the voltage at a specific emitter.
German organisation charged to test and to evaluate products, including power sources. See http://www.vde.com/vde_en/
See Plated Through Hole.
Unit of measurement of electromotive force or potential difference. Symbol E, in electricity; symbol V in semiconductor circuits. A current of 1 A passing through a resistance of 1 ohm will produce a potential difference of 1 volt. See Ohm's Law. Written as 'volt'. Abbreviated to V.
Rate of change of voltage over a period of time expressed in volts/microseconds.
In a control circuit, the on-time x the voltage applied to the winding is controlled (effectively running the magnetic component at peak magnetic flux density).
A circuit in the control of the pulse width modulator located in the primary which terminates the pulse when the volt seconds applied to the primary of the transformer exceeds a predetermined value.
A derivative electrical quantity, E, measured in the units volts and defined in terms of the independently obtained ampere, I, and the unit or Resistance, ohm (R) by Ohm’s Law E=IR.
The difference in magnitude, in percent, between differential tracking output voltages of a power supply (PSU) where the voltages have equal nominal values with opposite polarities.
See Clamp Circuit
Another name for Varistor.
Tapped or series resistance or impedance across a source voltage to produce a lower output voltage.
Difference in potential between two points in a passive component or circuit.
Maximum or minimum value in a voltage range.
Bounding circuit used to set specified maximum or minimum voltage levels.
The process of holding voltage constant between selected parameters, the extent of which is expressed as a percent. See also Regulation.
A power source that delivers constant voltage.
The use of a circuit or device to hold an output voltage constant within given limits.
Unit of Apparent Power.
Voltage Source Source. Negative supply voltage of a Field Effect Transistor. The doubled suffix indicates that the voltage is common. i.e. it is the supply voltage to one (or more) sources and not just the voltage at a specific source.
