capacitor Definition

ca·paci·tor (-tər)

noun

Elec. a device consisting of two or more conducting plates separated from one another by a dielectric nonconductor, as glass, mica, plastic, or dry air, used for storing an electric charge; condenser

capacitor Telecom Definition
An electrical device specifically designed to store an electrostatic charge, a capacitor is a system of conductors and dielectrics.A capacitor opposes changes in voltage, whereas an inductor opposes changes in current. See also capacitive reactance, conductor, current, dielectric, inductor, and voltage.
capacitor Usage Examples

Converse of object

  • smooth: Both of these things reduce the demands on the smoothing capacitor.
  • discharge: The hand pulling the weight down to ground level represents the action of the spark gap, periodically discharging the tank capacitor.
  • tune: Now rotate the tuning capacitor of the receiver under test through the broadcast band.
  • connect: At first we might be tempted to connect the tank capacitor directly across the output of the HVDC supply.

Preposition: in

  • parallel: This capacity can be built up by several smaller capacitors in parallel.

Adjective modifier

  • electrolytic: A bad hum usually means that the main electrolytic capacitors have come to the end of the road.
  • 100nf: In case of supply difficulties substitute components may be supplied; for instance 100nF capacitors may replace 47nF parts.
  • multilayer: Why do multilayer ceramic capacitors crack or burst into flames?
  • ferroelectric: Study of of 77 nm thick single crystal ferroelectric capacitors showing that the intrinsic response is exactly that of bulk.
  • ceramic: Many ceramic capacitors of high value show random small variations in value.
  • faulty: A power surge on the Bridge is rapidly and correctly diagnosed as a faulty capacitor by the highly-trained and competent engineering staff.

Modifies a noun

  • c1: The capacitor C1 is usually small compared with C2.
  • voltage: The peak primary current can be found by dividing the " fully charged " capacitor voltage by the surge impedance.
  • discharge: The alarm flashing lights seem to work via a capacitor discharge method.

Noun used with modifier

  • decoupling: Roughly 10 m of coax then fed into the other box were decoupling capacitors allowed signal take off for the mixer.
  • tantalum: The powder from which tantalum capacitors are made is of pure tantalum metal, with a typical particle size of 10µm.
  • feedthrough: Drill and deburr holes in the box for feedthrough capacitors for power connections.
  • by-pass: A resistance check should be made for a possible shorted screen by-pass capacitor that may be the cause for R-15 opening up.
  • polypropylene: Components are carefully chosen and include many polypropylene capacitors and Van den Hul internal wiring.
  • coupling: To prevent the transformer forming a DC short across the supply, an AC coupling capacitor is included.
