VARISTOR |
A metal (zinc) oxide over-voltage protective device. See METAL OXIDE ELEMENT. |
|

|
|
|
| |
VIA |
A small hole formed through the wafer or Printed Circuit Board and metallized, causing electrical connection to be made from the front (the side on which the circuitry is formed) to the backside of the wafer, substrate, or Printed Circuit Board. |

VOLT |
The unit of measurement of electromotive force necessary to produce one ampere of current in a circuit having a total resistance of one ohm. The volt is named for Alessandro Volta, an 18th century Italian physicist. |

VOLTAGE |
The electromotive force that exists across a voltage source (supply voltage) or a load in a circuit. Its unit of measurement is a volt. See ELECTROMOTIVE FORCE. |

VOLTAGE ARRESTOR |
A fast-acting, over-voltage protective device that can absorb or short a voltage to ground when the voltage is in excess of the device's rated value. |
